Abstract

KCa2P4H9O17 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 12-coordinate geometry to three H1+ and eight O2- atoms. There are a spread of K–H bond distances ranging from 2.87–2.96 Å. There are a spread of K–O bond distances ranging from 2.84–3.26 Å. There are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to seven O2- atoms to form CaO7 pentagonal bipyramids that share a cornercorner with one CaO7 pentagonal bipyramid, corners with five PO4 tetrahedra, edges with two equivalent CaO7 pentagonal bipyramids, and an edgeedge with one PO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.35–2.53 Å.
