Crystal structure ofcatena-poly[diammonium [di-μ-oxalato-cuprate(II)]]

Abstract

The structure of the title compound, {(NH4)2[Cu(C2O4)2]}n, at 100 K has monoclinic (P21/c) symmetry with the CuIIatom on an inversion center. The compound has a polymeric structure due to long Cu...O interactions which create [Cu(C2O4)2] chains along theaaxis. The structure also displays intermolecular N—H...O hydrogen bonding, which links these chains into a three-dimensional network.
