Abstract
The title compound, a new cyclodecaphosphate, was prepared by precipit ation from an aqueous solution of K10P10O30. The sparingly soluble sal t crystallizes monoclinic in the space group P21/a, with Z = 2, and th e unit-cell dimensions a = 14.546(10), b = 1 5.211 (10), c = 9.860(6) angstrom, beta = 105.12(4)degrees. The crystal structure was solved us ing 6501 unique reflections with a final R-value of 0.044. The centros ymmetrical ring anions rather distant from each other and arranged in a pseudo-tetragonal way create, parallel to the c direction, large cha nnels containing the water molecules.
