Poly[ethylenediammonium [cuprate(II)-μ₄-benzene-1,2,4,5- tetracarboxylato-k⁴ O:O′:O′′: O′′′] 2.5-hydrate]

چکیده مقاله

The asymmetric unit of the title compound, {(C2H10N2)[Cu(C10H2O8)] ·2.5H2O} n , contains one cuprate(II)-4-benzene-1,2,4,5-tetra-carboxyl- ate anion, one ethyl-ene-diammonium cation and two and a half water mol-ecules. The Cu atom is four-coordinated by four O atoms from four benzene-1,2,4,5-tetra- carboxyl-ate anions. Intra- and inter-molecular O - H⋯O and N - H⋯O hydrogen bonds in the formation of a supra-molecular structure. One of the water molecules is disordered equally over two sites. © International Union of Crystallography 2007.
