Abstract
Preparation and crystal structure of an acidic polyphosphate of calciu m is described. CaH2(PO3)(4): monoclinic, P2(1)/c, with Z = 2, and a = 5.686(1), b = 9.676(4), c = 8,844(3) Angstrom, beta = 92.35(2)degrees . The crystal structure was solved using 2321 unique reflections with a final R value of 0.017. The compound is characterized by infinite (P O3)(n) chains running along c and linked together in a three-dimension al way by Ca-O and hydrogen bonds. The two-dimensional linkage of the phosphoric chains by hydrogen bonds is compared to those already obser ved in ErH(PO3)(4) and BiH(PO3)(4).
