catena-Poly[[(pyridine-κN)copper(II)]-μ3-pyridine-2,6-dicarboxylato-κ3 O 2:O 2′,N,O 6:O 6′]
In the title compound, [Cu(C(7)H(3)NO(4))(C(5)H(5)N)](n), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensiona...
متن کاملPoly[μ2-aqua-diaqua(μ8-3-nitrobenzene-1,2-dicarboxylato)(μ6-3-nitrobenzene-1,2-dicarboxylato)tetrasodium]
In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit μ(8)- and μ(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. O...

The two independent Ni(II) ions in the one-dimensional title complex, [Ni(2)(C(7)H(3)NO(4))(2)(C(12)H(8)N(4)S)(H(2)O)(2)](n) or [Ni(2)(pydc)(2)(bpt)(H(2)O)(2)](n) (H(2)pydc = pyridine-2,6-dicarboxylic acid and bpt = 2,5-di-4-pyrid-yl-1,3,4-thia-diazole), have different coordination environments. One Ni(II) ion is in a slightly-distorted octa-hedral coordination environment formed by three O ato...
متن کاملStructure and optoelectronic properties of helical pyridine-furan, pyridine-pyrrole and pyridine-thiophene oligomers.
Density functional theory based calculations have been carried out to systematically investigate the structural and optoelectronic properties of pyridine-furan, pyridine-pyrrole and pyridine-thiophene oligomers. Comparison of results obtained at B3LYP/6-31G(d) and B3LYP-D3/6-31G(d) levels of theories reveals that the inclusion of dispersion correction with the B3LYP functional has a major impac...
متن کاملElectrochemistry in Pyridine-iv. Chemical and Electrochemical Reduction of Pyridine”
The cathodic polarographic wave observed for solutions of AlCl, in pyridine is due not to reduction of Al(III), but to reduction of the solvent, in which process Al(II1) plays an essential role, apparently by polarizing the pyridine through the formation of a Lewis acid-base adduct with the pyridine nitrogen. Macroscale electrolysis of pyridine solutions of AlCl, at a mercury cathode results in...
