Heterobimetallic Cu(II)-Hg(II) polynuclear complexes containing Hg(SCN)42- unit – Synthesis, spectroscopic investigations, X-ray studies and magnetic properties

Three novel heterobimetallic polymers with Hg(SCN)42- as a linker have been synthesised and characterized by means of IR, EPR, magnetic measurements and single crystal X-ray. All the obtained compounds [Cu(bpzm)Hg(SCN)4]n (1), [Cu(bdmpzm)Hg(SCN)4]n (2) and [Cu(dpa)Hg(SCN)4]n (3) form supramolecular framework structures. The 1 creates a three-dimensional coordination polymer, and 2 and 3 form two-dimensional nets extending along crystallographic (0 1 0) plane. Each octahedrally coordinated Cu(II) atom of 1 connects to four mercury ions through four thiocyanate bridges, and each Hg(II) ion is bridged with four copper ions via four thiocyanate bridges. The Cu(II) ions of 2 and 3 display a pyramidal coordination geometry, and they are connected to three mercury ions through three thiocyanate bridges, one thiocyanate ion is nonbridging group.

Ternary compounds formed between M , adenosine 5′-triphosphate , and bis(2-pyridyl)amine(bipyam) have been prepared The solid compounds are crystalline and have a stoicheiometry described by the formula M(Hatp)(Hbipyam)*nH2O (n = 2-9).X-ray powder diffraction patterns are similar.Potentiometric titrations in aqueous solution show the presence of two ionizable protons.Visible spectra suggest an octahedral co-ordination geometry.I.r. spectra indicated essentially the same type of metal-ligand interactions in all the complexes and show that Hatp(3-) co-ordinates to the metal through the oxygen atoms of the alpha, beta, and gamma phosphate groups.The ternary compounds where M = Mg(II)(1) or Ca(II)(2) have been studied by single-crystal X-ray diffration techniques and their molecular structures determined.The two species are isostructural and can be formulated as 22*9H2O (2).Both (1) and (2) crystallise in space group C2221 (Z = 4), with a = 22.734(3), b = 10.233(3), c = 30.997(4) Angstroem for (1) and a = 22.965(3), b = 10.154(3), c = 32.390(4) Angstroem for (2).X-ray diffraction data were collected on a Philips automatic diffractometer and the structures solved by direct methods using the SIR (Semi-invariant Representation) package and refined by full-matrix least squares to final R values of 0.111 and 0.124 (1 088 and 1 008 independent observed reflections) for (1) and (2) respectively.In the (4-) units the metal ions lie on a two-fold axis with an octahedral co-ordination geometry completed by the oxygen atoms of the alpha, beta, and gamma phosphate groups of two symmetry-related Hatp(3-) molecules.The co-ordination polyhedron of (1) is nearly regular but in (2) it is significantly distorted.The phosphate chains have a folded configuration in both (1) and (2).In both complexes there are no bonding interactions between the metal ions and the adenine base.The metal atoms of the (2+) cations are also located on two-fold axes while the six co-ordinated water molecules form hydrogen bonds with the phosphate chains.The Hbipyam(1+) molecules do not co-ordinate to the metal ions and are disordered around two-fold axes.Strong stacking interactions exist between Hbipyam(1+) and purine rings.

Excited state dynamics of symmetric and asymmetric Cr3(dpa)4Cl2 measured using femtosecond transient absorption spectroscopy

Herein, the excited-state dynamics of an extended metal atom chain complex, Cr3(dpa)4Cl2 (dpa = dipyridylamide), in tetrahydrofuran solution were investigated using femtosecond transient absorption spectroscopy. Upon excitation at a wavelength of 330 nm, two distinct excited-state absorption species with varied dynamics were identified and assigned to the symmetric (s-) and unsymmetric (u-) Cr3(dpa)4Cl2. The major species is s-Cr3(dpa)4Cl2 that undergoes rapid conversion at less than 100 fs from the ligand-centred pi-pi? state, which is the initially accessed state, to the metal-centred d-d state and then vibrational cooling accompanying the structural relaxation at a time constant ?2.2 ps. Most of the s-form is recovered to the ground state at ?200 ps. For u-Cr3(dpa)4Cl2, a similar rapid conversion to d-d states is observed, and the geometric/vibrational relaxation is ?0.8 ps. The second recovery of the ground state with approximately equal amplitude is observed at a time constant of ?5 ns. This might be because many d-d states exist and about half of them inefficiently couple with the ground state surface.

Palladium-catalyzed synthesis of trans-4-(N,N-Bis(2-pyridyl)amino)stilbene. A new intrinsic fluoroionophore for transition metal ions

(formula presented) The title compound (1) has been synthesized via sequential Pd-catalyzed amination reactions and investigated as an intrinsic fluoroionophore. The efficiency in the synthesis of 1 strongly depends on the order of couplings among the substrates. Compound 1 displays fluorescence quenching upon the binding of transition metal ions, where the binding-triggered conformational twisting and in turn the inhibition of internal charge transfer (ICT) play an important role.

Cobalt(II) complexes of sparfloxacin: Characterization, structure, antimicrobial activity and interaction with DNA and albumins

The cobalt(II) complexes with the quinolone sparfloxacin (Hsf) in the absence or presence of the nitrogen-donor heterocyclic ligands 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2?-bipyridylamine (bipyam) were prepared and characterized physicochemically and spectroscopically. The crystal structures of complexes [Co(sf)2(bipy)]?3MeOH?2H2O and [Co(sf)2(phen)]?4MeOH were determined by X?ray crystallography. The antimicrobial activity of the complexes was tested against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis) and was found similar or higher than that of free Hsf. The binding of the complexes to calf-thymus DNA was monitored by UV-vis spectroscopy and DNA-viscosity measurements and indirectly by competitive studies with ethidium bromide; intercalation is suggested as the most possible interaction mode. Fluorescence emission spectroscopy was used to evaluate the interaction of the complexes with human or bovine serum albumin and the corresponding binding constants were determined.
