Cu 3(PO 4) 2 · H 2O: Synthese und Kristallstruktur
Abstract
Crystals of Cu 3(PO 4) 2 · H 2O were synthesized under hydrothermal conditions. They crystallize in space group C2/ c with a = 18.05(2), b = 6.20(1), c = 12.26(2) Å, β = 105.50(5)° ( Z = 8). The crystal structure was solved from 1834 independent two-circle diffractometer X-ray data by direct methods and Fourier summations and was refined by full-matrix least-squares techniques to R = 0.033. The copper atoms are [4 + 2], [4 + 1], and [4] coordinated. These coordination polyhedra are connected by oxygen atom corners and O-O edges building a two-dimensional sheet-like framework parallel [100]. Linking these frameworks with [PO 4] 3- groups and hydrogen bonds results in a three-dimensional network.
