Abstract

Hydrothermal reactions of Ca(NO3)2·4H2O and the appropriate xylyldiphosphonic acid provided crystals of [Ca(p-C8H8P2O6H2)(OH2)3]n (1), [Ca(m-C8H8P2O6H2)(OH2)2]n (2), and [Ca(o-C8H8P2O6H2)(OH2)]n (3). The juxtaposition of phosphonate donor groups on the xylyl-diphosphonate linkers is a major structural determinant. Thus, the structure of [Ca(p-C8H8P2O6H2)(OH2)3]n (1) is three dimensional, while [Ca(m-C8H8P2O6H2)(OH2)2]n (2) and [Ca(o-C8H8P2O6H2)(OH2)]n (3) exhibit reduced dimensionalities, one- and two-dimensional, respectively. The structures exhibit variable coordination numbers, as well as variable numbers of coordinated water molecules. In addition, hydrogen bonding plays an important role in the structural chemistry of these materials.
