In this paper we describe a new copper diphosphonate compound [NH2(C2H4)2NH2]Cu3(hedp)2(H2O)4(hedp=1 hydroxyethyli denediphosphonate, CH3C(OH)(PO3)2) synthesized under hydrothermal conditions. Single crystal structure determination reveals that the compound contains anionic ladder like chains of {Cu3(hedp)2(H2O)4}n which are linked by moderately strong inter chain hydrogen bonds, forming a supramolecular layer. The protonated piperazine fill the spaces between the layers.
