The replacement of the iodide ligands in the complex [PtI2(dpa)] (1) (dpa is 2,2?-dipyridylamine) by silver triflate in acetonitrile afforded the compound [Pt(dpa)(MeCN)2](SO3CF 3)2 (2). Homoleptic complexes [Pt(dpa)2](X) 2 (3·(X)2) were synthesized by the treatment of [PtI2(dpa)] (1) with 2,2?-dipyridylamine in the presence of silver salts AgX in methanol (X = NO3) or acetonitrile (X = SO 3CF3). The deprotonation of the complex [3](SO 3CF3)2 to give the homoleptic complex [Pt(dpa-H)2] (4) was performed by two methods, e.g., by the treatment of [3](SO3CF3)2 with 2 equiv. of NaOH in methanol or by the addition of excess Et3N to a suspension of [3](SO3CF3)2 in methanol. The structures of compounds 1-4 were established by elemental analyses, high resolution electrospray ionization mass spectrometry, IR and NMR spectroscopy; the crystal structure of complexes [2](SO3CF3)2, [3](NO3)2·H2O, [3](SO3CF 3)2·2H2O, and 4 were determined by single-crystal X-ray diffraction.

The interaction of the non-steroidal anti-inflammatory drugs naproxen or mefenamic acid with MnCl2 in the presence of the nitrogen-donor ligands 2,2?-bipyridine, 1,10-phenanthroline, 2,2?-bipyridylamine or pyridine resulted in the formation of one dinuclear and four mononuclear Mn(ii) complexes. The complexes were characterized by diverse physicochemical and spectroscopic techniques and single-crystal X-ray crystallography. The biological activity of the complexes was evaluated in regard to their ability to scavenge the free radicals of 1,1-diphenyl-2-picrylhydrazyl, 2,2?-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and hydroxyl and their binding affinity towards calf-thymus (CT) DNA and serum albumins. The complexes exhibit noteworthy scavenging activity towards ABTS and hydroxyl radicals; they can bind tightly to CT DNA via intercalation and can bind to bovine or human serum albumins tightly and reversibly.

Eleven crystal structures have been determined for the trinuclear Co 3(dpa)4Br2 (1) (dpa = di(2-pyridyl)amide anion) molecule in the following solvates: 1·CH2Cl2 (at 111, 147 and 240 K), 1·C6H12 (at 110, 150, 213 and 298 K) and 1·1.75C7H8·0.5C6H 14 (at 110, 170, 213 and 295 K). Their magnetic behavior has been measured over the temperature range 5-350 K. In nearly every respect their behavior closely parallels that of their chloro analogs, although certain crystallographic and magnetic details differ. Of particular importance is that both symmetrical and unsymmetrical structures are observed in different crystalline forms and that the unsymmetrical forms display marked temperature dependence. It is, therefore, clear that the highly unconventional behavior of the chloro analog is not restricted to that one compound. The Royal Society of Chemistry 2001.

A series of blue luminescent zinc(II) complexes, [Zn(dpa)X2] [dpa = di-2-pyridylamine, X = OAc 1a, Cl 1b, CN 1c or 4-MeC6H4S 1d], [Zn(dpa)2][CF3SO3]2 2, [Zn(tpda)X2] [tpda = 2,6-bis(2-pyridylamino)pyridine, X = OAc 3a or Cl 3b] and [Zn(tpda)(CF3SO3)2] 4 has been prepared. Their molecular structures, except complex 4, have been established by X-ray crystallography. In the crystal lattice of 2 the [Zn(dpa)2]2+ cations and CF3SO3- anions are disposed in pairs via intermolecular hydrogen bonds [N(2)…O(2) 2.865(4) A]. The crystal packing of [Zn(dpa)(OAc)2] 1a revealed that two adjacent molecules associate in pairs through intermolecular hydrogen bonding [N(2) …O(4?) 2.816(3) A]. However, the crystal lattice of its tpda derivative 3a shows that the molecules are linked by extensive intermolecular hydrogen bonding between the amino groups and the acetate ligands [N(2)…O(2?) 2.805(3) and N(4)…O(4?) 2.860(3) A] resulting in an interlocking hydrogen bond network. Polymeric one-dimensional tapes are generated through extended pi-pi stacking interactions between the molecules of [Zn(dpa)(4-MeC6H4S)2] 1d, and the thiolate groups are aligned in an all-anti conformation along the metal chain. In the case of [Zn(dpa)(CN)2] 1c, co-operative intermolecular hydrogen bonds and aromatic pi-pi interactions in its solid state lead to a supramolecular two-dimensional sheet. All the zinc(II) complexes display high energy intraligand 1(pi-pi*) fluorescence in degassed MeOH at 298 K, and intraligand 3(pi-pi*) phosphorescence in a glassy solution (MeOH-EtOH 1:2 at 77 K). An emission band observed for 1c (418 nm) and 1d (481 nm) in their solid state emission spectra is ascribed to excimeric emission due to aromatic pi-pi interactions.

By introducing two carrier-transporting moieties (oxadiazole and carbazole) into two diimine ligands (2-(2-pyridine)-benzimidazole and 2,2′-dipyridylamine), respectively, four novel ligands (L1-L4) and their corresponding rhenium(I) complexes (1-4) have been synthesized and characterized by elemental analysis, 1H NMR and IR spectra. Their photophysical properties, thermal analysis, along with the X-ray crystal structure analysis of L4 and corresponding complex 4 are also described. In absorption spectra, the 2-(2-pyridine)-benzimidazole containing complexes 1, 2 show the intraligand charge-transfer (pi?pi*(L)) bands and metal-to-ligand charge-transfer dpi(Re)?pi*MLCT bands, while the 2,2′-dipyridylamine containing complexes 3, 4 only show the pi?pi*bands. In the excitation spectra, all the complexes show strong MLCT bands. After excitation of pi?pi*or MLCT bands, all the four Re(I) complexes exhibit broad bands around 550-560nm due to the Re(I)-based 3MLCT emission. The two complexes 1 (with oxadiazole moiety) and 2 (with carbazole moiety) show the photoluminescence quantum efficiency of 2.0% and 7.5% in solid state, respectively, indicating that the carbazole unit is the better chromophore to enhance the luminescence efficiency of diimine Re(I) complexes than the oxadiazole moiety.

Five new structures of HgII complexes containing Hdpa ligands have been determined. With halides, tetrahedral HgII is constructed by a Hdpa and two chlorides or bromides, and strong hydrogen bonds between amine hydrogen atoms and halide atoms provide dimeric compounds. With benzoates, distorted octahedral HgII is constructed by a Hdpa and two chelating benzoate ligands, and hydrogen bonding and pi-pi interactions provide a polymeric compound. With nitrates or perchlorates, two dpa ligands bridge two HgII ions, and counter-anions axially coordinate to HgII ions to form a polymeric compounds. In addition, all five HgII complexes showed the intense emissions at room temperature, which are red-shifted compared to the corresponding ligand. Moreover, 3 and 4 have shown efficient catalytic transesterification recation, while 1, 2 and 5 has displayed a very slow conversion.

The iodide-abstraction reaction of <2>2 1 (bipy = 2,2′-bipyridyl, R = p-tolyl) with AgPF6 in MeCN gave 2 2 which slowly decarbonylated at room temperature to 2 3.The crystal structure of 3 shows a Rh-Rh single bond <2.534(2) Angstroem> and one of the three terminal nitrile ligands axially attached to the bipy-bound rhodium atom.Complex 3 reacts with Na*2H2O to give 4.In CH2Cl2, the iodide-abstraction reaction of 1 affords a green solution containing a carbonyl complex (2+) A (solv = CH2Cl2), an analogue of 2.Complex A (solv = CH2Cl2) reacted with neutral chelating lgands to give the carbonyl-bridged complexes 2 the last of which undergoes reduction with NaBH4 to give paramagnetic 11 having a face-to-face structure with a monodentate dppe ligand.With Ph2PCH2PPh2 (dppm), A (solv = CH2Cl) afforded 2 10a X-ray studies on which, as a CH2Cl2 solvate, reveal a carbonyl-bridged open-book structure with a Rh-Rh distance of 3.179(2) Angstroem and a large Rh-C(O)-Rh angle of 108.3 deg.Complex 10a equilibrates with the face-to-face, terminal carbonyl isomer 2 10b in solution.The electronic structures of the two isomers have been probed by extended-Hueckel molecular-orbital calculations on the model compound .These show (i) the absence of metal-metal bonding in 10a while 10b has a Rh-Rh ? bond, and (ii) that the CO in 10a is best viewed as more ketonic than a typical bridging carbonyl.The reaction of complex A (solv = CH2Cl2) with neutral chelating ligands also gives low yields of <2> 12 the crystal structure of which shows two dirhodium fragments linked by two O2PF2 groups bridging across axial and equatorial sites in different (4+) moieties.The reaction of A (solv = CH2Cl2) with N-SH ligands yields (N-S = 1-methyl-2-sulfanylimidazolate 13, 2-sulfanylpyrimidinate 14, 2-sulfanylthiazolinate 15, or 2-sulfanylbenzimidazolate 16), and NaX gives (X = Cl or NO2).
