Abstract
The structure of the title compound, {(NH(4))(2)[Cu(C(2)O(4))(2)]} (n) , at 100 K has monoclinic (P2(1)/c) symmetry with the Cu(II) atom on an inversion center. The compound has a polymeric structure due to long Cu⋯O inter-actions which create [Cu(C(2)O(4))(2)] chains along the a axis. The structure also displays inter-molecular N-H⋯O hydrogen bonding, which links these chains into a three-dimensional network.
