摘要
In this paper we describe a new copper diphosphonate compound [NH2 (C2H4) 2NH2] Cu-3 (hedp)2(H2O) 4 (hedp = 1-hydroxyethylidenediphosphonate, CH3C(OH)(PO3)(2)) synthesized under hydrothermal conditions. Single crystal structure determination reveals that the compound contains anionic ladder-like chains of [Cu-3(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.
