Abstract

Crystals of the title compound, calcium dipotassium diphos­phate, have been synthesized from a melt and structurally characterized using single-crystal X-ray diffraction. The CaK2P2O7 structure can be described as a layer structure, with alternating [K2P2O72−]∞ and [Ca2+]∞ layers parallel to the ab plane. Ca2+ is coordinated by six O atoms in a distorted octahedron. K+ is coordinated by nine O atoms in two different polyhedra.
