Abstract
The crystal and molecular structure of bis(aminomethylphosphonate)-copper(II), C2H10N2O6P2Cu, has been determined from MoKα diffractometer data. The compound crystallizes in the monoclinic space groupP21/n witha =7.571(2),b = 4.943(1),c = 11.212(3) Å, β = 105.84(2) °, andZ = 2. The structure was solved by the heavy-atom technique and refined by full-matrix least-squares methods toR = 0.041, using 1084 reflections for which ¦F o¦ > 3.92 σ (¦F o¦). In this complex, the Cu atom is square-planar coordinated by four O atoms from four phosphonic groups, and not by the amino group. The Cu-O bond lengths are 1.928(3) and 1.937(3) Å, and the phosphonic groups bridge adjacent Cu atoms in polymeric chains. The infrared spectrum of this complex is reported.
