Bis(imidazolium) di--pyrazole-3,5-dicarboxylato(3-)-bis[diaquazinc(II)]

J.-F. Zhang and X.-H. Li

Abstract: In the title compound, (C₃H₅N₂)₂[Zn₂(C₅HN₂O₄)₂(H₂O)₄], two 3,5-pyrazoledicarboxylate trianions and two water molecules are coordinated to the Zn atom and the geometry is octahedral. Each pair of Zn^II ions is bridged by two 3,5-pyrazoledicarboxylate trianions, forming a centrosymmetric binuclear complex dianion. In the crystal structure, the cations and anions are linked by O-HO and N-HO hydrogen bonds to form a network structure.
