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-pyrid­yl)pyrazole mol­ecule. A second, symmetry-generated, oxalate ion completes a distorted cis-NiN(2)O(4) octa­hedral geometry for bot...

Descripción
Sumario: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-pyrid­yl)pyrazole mol­ecule. A second, symmetry-generated, oxalate ion completes a distorted cis-NiN(2)O(4) octa­hedral 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.
