Abstract : The asymmetric unit of the title compound, {[Cu(C4H2O4)(C3H10N2)(H2O)] ·H2O} n , consists of two CuII atoms, half each of two propane-1,3-diamine ligands and two coordinated water mol-ecules, all lying on crystallographic mirror planes, also one fumarate dianion and one uncoordinated water mol-ecule in a general position. The Cu(C3H10N2)(H2O) units are linked via fumarate dianions into a zigzag chain running along the a axis. A longer Cu - O distance [2.873 (3) Å] is to a water mol-ecule bridging equivalent CuII atoms in adjacent chains, forming a three-dimensional framework. One of the CuII atoms is in a distorted square-pyramidal environment and the other is in a pseudo-octa-hedral geometry of the [5+1] type. O - H⋯O and N - H⋯O hydrogen bonds are observed in the crystal structure.
