Structural and EPR studies of pyrophosphate-bridged dinuclear Cu II complexes

Highly Thermally and Chemically Stable Nickel(II) Coordination Polymers: Tentative Studies on Their Sorption, Catalysis, and Magnetism

The five new Ni(II) coordination polymers (CPs) {[Ni(bitp)(bpe)0.5(H2O)2]¡¤0.5bpe}n (1), {[Ni(bitp)(bpa)0.5(H2O)2]¡¤0.5bpa}n (2), {[Ni(bitp)(4,4?-bpy)0.5(H2O)]¡¤H2O}n (3), {[Ni1.5(bitp)(Hbitp)(2,2?-bpy)(H2O)]¡¤3H2O}n (4), and [Ni(bitp)(bipyam)]n (5), where H2bitp = 2-(benzimidazol-1-yl)terephthalic acid, bpe = 1,2-bis(4-pyridyl)ethylene, bpa = 1,2-bis(4-pyridyl)ethylane, 4,4?-bpy = 4,4?-bipyridine, 2,2?-bpy = 2,2?-bipyridine, and bipyam = 2,2?-bipyridylamine, were prepared under the same hydrothermal environments except for various N-donor ligands which can effectively regulate the structures of the complexes. For the bridging N-donor ligands bpe, bpa, and 4,4?-bpy, isostructural 1 and 2 feature three-dimensional (3D) layered-pillared frameworks with one-dimensional (1D) channels that house free bpe or bpa, while 3 is a wavelike two-dimensional (2D) stacked layer with similar 4,4?-bpy bridging auxiliary ligands. However, when terminal ligands 2,2?-bpy and bipyam are used, 2D 4 and 1D ladder chains 5 are obtained, respectively. Interestingly, 1-5 exhibit outstanding thermostability (up to 320 C) and chemical stabilities (against boiling water, acids, bases, and organic solvents). Furthermore, on the basis of their highly thermal and chemical stability, tentative studies on the structures and properties (such as adsorption, catalysis, and magnetic properties) were undertaken. The gas sorption measurements show that 1 and 2 exhibit high adsorption selectivity of CO2 over CH4. The catalytic reactions demonstrate the role of catalysts 1-5 to synthesize 3,6-bis(pyridin-4-yl)-1,2,4,5-tetrazine. The magnetic analyses indicate that there exist a zero field splitting (ZFS) on the Ni(II) ions in 1-5.

Structural and magnetic properties of Co3(dpa) 4Br2

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.

Structure and magnetism of a binuclear CuII pyrophosphate: Transition to a 3D magnetic behaviour studied by single crystal EPR

A binuclear CuII compound [Cu2(bpa)2(P2O7)(H2O)2]¡¤2.5H2O, 1, (bpa = 2,2?-bipyridylamine), with pairs of CuII ions bridged by one pyrophosphate tetra-anion, was synthesized and crystallized. Its triclinic structure was determined by single-crystal X-ray diffraction. Electron paramagnetic resonance (EPR) spectra of single crystal samples of 1 were recorded for a fixed orientation of the magnetic field (B0) as a function of temperature (T) between 4.7 and 293 K, and at T = 4.7, 50 and 293 K, as a function of the orientation of B0. Below ?8 K, the spectra are assigned to two types of mononuclear crystal defects hyperfine-coupled to one copper and two nitrogen nuclei. The g-matrices and hyperfine couplings at these T provide information about the structures of these defects. Above 10 K, the spectrum is dominated by the response of the bulk binuclear CuII material, showing hyperfine interactions with two copper nuclei, collapsing to a single peak above 18 K when the units are magnetically connected, and the magnetic behaviour becomes 3D. We attribute the results above 10 K to the interplay of an AFM intrabinuclear exchange interaction J0 = -28(3) cm-1 (defined as ex = -J0S1¡¤S2), and three orders of magnitude weaker exchange coupling with average magnitude J1? 0.022 cm-1 between CuII ions in neighbouring binuclear units. The interplays between structure, exchange couplings, magnetic dimension and spin dynamics in the binuclear compound are discussed. A previously unreported situation, where the structure of the spectra arising from the anisotropic spin-spin interaction term (D) within the binuclear unit is averaged out, but the forbidden half field transition is not, is observed and explained.

Synthesis, characterisation and biological properties of gold(iii) compounds with modified bipyridine and bipyridylamine ligands

Square planar gold(iii) complexes that contain functionalised bipyridine ligands of general formula [Au(NN)Cl2][PF6] [where NN = 2,2?-bipyridine, 4,4?-dimethyl-2,2?-bipyridine, 4,4?-dimethoxy-2,2?-bipyridine and 4,4?-diamino-2,2?- bipyridine] have been prepared and characterised by NMR spectroscopy and mass spectrometry. Two of the complexes have also been characterised in the solid state by X-ray crystallography. In addition, a gold(iii) compound bearing a dipyridin-2-ylamine ligand was also prepared and characterised. The complexes were found to undergo hydrolysis under pseudo-physiological conditions. Moreover, the complexes showed moderate to good cytotoxicity in vitro towards the A2780 human ovarian carcinoma cell line and the cisplatin resistant variant A2780cisR. Reactivity studies with biomolecules, such as reducing agents, plasmid DNA and a model protein (ubiquitin) were also performed to provide tentative insights into the mode of action of the complexes.
