Mt. Averbuchpouchot et al., THE CALCIUM-POTASSIUM CYCLODECAPHOSPHATE HEXADECAHYDRATE - CA4K2P10O30-CENTER-DOT-16H(2)O, European journal of solid state and inorganic chemistry, 33(11), 1996, pp. 1091-1100
We describe the chemical preparation and crystal structure of a mixed
calcium-potassium cyclodecaphosphate: Ca4K2P10O30.16H(2)O. This compou
nd is orthorhombic, Pna2(1), with Z = 4 and the following unit-cell di
mensions: a = 14.773(2), b = 15.758(3), c = 19.9141(2) Angstrom. This
salt presents a strong pseudo-centrosymmetry.
