Materials Data on Eu(CdP)2 by Materials Project
Eu(CdP)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Eu2+ is bonded to six equivalent P3- atoms to form EuP6 octahedra that share corners with twelve equivalent CdP4 tetrahedra, edges with six equivalent EuP6 octahedra, and edges with six equivalent CdP4 tetrahedra. All Eu–P bond lengths are 3.06 Å. Cd2+ is bonded to four equivalent P3- atoms to form CdP4 tetrahedra that share corners with six equivalent EuP6 octahedra, corners with six equivalent CdP4 tetrahedra, edges with three equivalent EuP6 octahedra, and edges with three equivalent CdP4 tetrahedra. The corner-sharing octahedra tilt angles range from 16–55°. There are three shorter (2.65 Å) and one longer (2.81 Å) Cd–P bond lengths. P3- is bonded to three equivalent Eu2+ and four equivalent Cd2+ atoms to form a mixture of distorted edge and corner-sharing PEu3Cd4 pentagonal bipyramids.
