Catena-Poly[[[[3-(2-pyrid-yl)-1H-pyra-zole]nickel(II)]-?-oxalato] sesquihydrate].

ABSTRACT: In the title compound, {[Ni(C(2)O(4))(C(8)H(7)N(3))]·1.5H(2)O}(n), both unique Ni(II) ions are chelated by an O,O'-bidentate oxalate ion and an N,N'-bidentate 3-(2-pyrid-yl)pyrazole mol-ecule. A second, symmetry-generated, oxalate ion completes a distorted cis-NiN(2)O(4) octa-hedral geometry for both metal centres. The bridging oxalate ions result in two distinct wave-like polymeric chains propagating in [100]. The packing is consolidated by N-H?O and O-H?O hydrogen bonds. The crystal studied was found to be an inversion twin.

Project description:In the title compound, [Mn(C2O4)(C10H7N3S)] n , the Mn(II) cation is chelated by one 2-(1,3-thia-zol-4-yl)-1H-benzimidazole ligand and two oxalate anions in a distorted N2O4 octa-hedral geometry. Two independent oxalate anions are located on individual inversion centers and bridge the Mn(II) cations into a polymeric chain running along [101]. The thia-zole ring is approximately coplanar with the benzimidazole ring system [dihedral angle = 4.19?(9)°]. In the crystal, classical N-H?O hydrogen bonds and weak C-H?O hydrogen bonds link the polymeric chains into a three-dimensional supra-molecular architecture.

Project description:In the title compound, {[Ni(C(12)H(10)N(2))(H(2)O)(4)](NO(3))(2)}(n), the Ni(II) ion, lying on a crystallographic inversion center, has a distorted octa-hedral coordination sphere comprising four water ligands and two N-atom donors from the trans-related 1,2-bis-(4-pyrid-yl)ethene ligands, which also have crystallographic inversion symmetry.
