The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along ...

In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Tw...

Abstract Nonsteroidal anti-inflammatory drugs (NSAIDs) and coxibs are traditional medicines for the treatment of inflammation, yet associated with serious side effects. Hence, need discovering novel compounds valuable clinical benefits is great importance. In this study, 18 derivatives p-nitrophenyl hydrazones were docked against COX-2, 5-LOX, H+/K+ ATPase, followed by predicting their drug-lik...

In the title complex, {[Ni(2)(C(14)H(4)N(2)O(8))(H(2)O)(6)]·2H(2)O}(n), the two Ni(II) atoms are located in different special positions (one on a twofold rotation axis and the second on a centre of symmetry) and have different distorted octa-hedral environments (one by two N atoms from a bipyridine unit, two O atoms from two water mol-ecules and two O atoms from two carboxyl-ate groups, and the...

In the title compound, [Ni(C(12)H(7)N(2)O(4))(2)]·4H(2)O, the Ni atom is located at the centre of a distorted octa-hedron, formed by four N atoms and two O atoms from the same two tridentating chelated 6-carb-oxy-2,2'-bipyridine-6'-carboxyl-ate (L) ligands. Face-to-face π-stacking inter-actions between inversion-related pyridine rings with centroid-centroid distances of 3.548 (3) and 3.662 (3) ...

The reaction of alkaline earth pentacyanocyclopentadienides with 4,4′-bipyridine in MeOH yielded undefined products composition [M(PCC)2(Bipy)x(MeOH)y(H2O)z] (PCC = [C5(CN)5]−). Recrystallization from MeOH, EtOH, or n-BuOH gave crystals [Mg(H2O)4(4,4′-bipy)2](PCC)2∙2BuOH (1), [Ca(H2O)4(4,4′-bipy)2](PCC)2∙(4,4′-bipy) (2), [Sr(MeOH)8](PCC)2∙3(4,4′-bipy) (3), [Sr2(H2O)4(BuOH)4(PCC)2(µ-PCC)2 (µ-4,4...

We report new divalent osmium complexes that feature strong red metal-to-ligand-charge-transfer (MLCT) phosphorescence and electrophosphorescence. The general formula of the complexes is Os(II)(N-N)(2)L-L, where N-N is either a bipyridine or a phenanthroline and L-L is either a phosphine or an arsine. New polypyridyl ligands synthesized are 4,4'-di(biphenyl)-2,2'-bipyridine (15) and 4,4'-di(dip...
