Abstract

CaMg5CP3O16 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ca is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.32–2.74 Å. There are five inequivalent Mg sites.

There are a spread of Mg–O bond distances ranging from 2.07–2.15 Å. In the second Mg site, Mg is bonded to six O atoms to form distorted MgO6 octahedra that share corners with two PO4 tetrahedra, a cornercorner with one MgO5 trigonal bipyramid, edges with two MgO6 octahedra, and an edgeedge with one MgO6 pentagonal pyramid.
