Materials Data on Ca3Zn2(CuP2)2 by Materials Project
Ca3Zn2(CuP2)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six P3- atoms to form CaP6 octahedra that share corners with six equivalent CaP6 octahedra, corners with six equivalent ZnP4 tetrahedra, edges with six equivalent CaP6 octahedra, edges with three equivalent ZnP4 tetrahedra, and a faceface with one CaP6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are three shorter (2.94 Å) and three longer (3.05 Å) Ca–P bond lengths. In the second Ca2+ site, Ca2+ is bonded to six equivalent P3- atoms to form a mixture of corner, edge, and face-sharing CaP6 octahedra. The corner-sharing octahedral tilt angles are 45°. All Ca–P bond lengths are 3.06 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent P3- atoms. All Cu–P bond lengths are 2.33 Å. Zn2+ is bonded to four equivalent P3- atoms to form ZnP4 tetrahedra that share corners with six equivalent CaP6 octahedra, corners with six equivalent ZnP4 tetrahedra, edges with three equivalent CaP6 octahedra, and edges with three equivalent ZnP4 tetrahedra. The corner-sharing octahedra tilt angles range from 20–53°. There are three shorter (2.44 Å) and one longer (2.54 Å) Zn–P bond lengths. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 3-coordinate geometry to six Ca2+ and three equivalent Cu1+ atoms. In the second P3- site, P3- is bonded to three equivalent Ca2+ and four equivalent Zn2+ atoms to form distorted edge-sharing PCa3Zn4 pentagonal bipyramids.
