Materials Data on Th(CuP)2 by Materials Project
Th(CuP)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Th4+ is bonded to six equivalent P3- atoms to form ThP6 octahedra that share corners with twelve equivalent CuP4 tetrahedra, edges with six equivalent ThP6 octahedra, and edges with six equivalent CuP4 tetrahedra. All Th–P bond lengths are 2.90 Å. Cu1+ is bonded to four equivalent P3- atoms to form CuP4 tetrahedra that share corners with six equivalent ThP6 octahedra, corners with six equivalent CuP4 tetrahedra, edges with three equivalent ThP6 octahedra, and edges with three equivalent CuP4 tetrahedra. The corner-sharing octahedra tilt angles range from 22–53°. All Cu–P bond lengths are 2.40 Å. P3- is bonded to three equivalent Th4+ and four equivalent Cu1+ atoms to form a mixture of distorted edge and corner-sharing PTh3Cu4 pentagonal bipyramids.
