Abstract

In the title compound, [Cu2Mn(C5HN2O4)2(H2O)6]n, the CuII ion is coordinated by two N atoms, two O atoms and one water O atom in a distorted square-pyramidal geometry. The MnII ion is coordinated by two O atoms and four water O atoms in a distorted octahedral geometry. Two pyrazolyl-3,5-dicarboxylate anions chelate to two copper ions, forming a dinuclear unit, which further connects the MnII ions into chains extending along [100]. Both independent coordinated water molecules on the MnII ion are disordered in a 50:50 fashion.
