Title: Materials Data on CuGe2P3 by Materials Project

Abstract

CuGe2P3 is Enargite-like structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Cu1+ is bonded to four P3- atoms to form CuP4 trigonal pyramids that share corners with six GeP4 tetrahedra and corners with six equivalent CuP4 trigonal pyramids. There are three shorter (2.27 Å) and one longer (2.30 Å) Cu–P bond lengths. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four P3- atoms to form GeP4 tetrahedra that share corners with nine GeP4 tetrahedra and corners with three equivalent CuP4 trigonal pyramids. All Ge–P bond lengths are 2.42 Å. In the second Ge4+ site, Ge4+ is bonded to four P3- atoms to form GeP4 tetrahedra that share corners with nine GeP4 tetrahedra and corners with three equivalent CuP4 trigonal pyramids. There are one shorter (2.27 Å) and three longer (2.44 Å) Ge–P bond lengths. There are three inequivalent P3- sites. In the first P3- site, P3- is bonded to one Cu1+ and three equivalent Ge4+ atoms to form PCuGe3 tetrahedra that share corners with nine PCuGe3 tetrahedra and corners with three equivalent PCu3Ge trigonal pyramids. In the second P3- site, P3- is bonded to four Ge4+ atoms tomore » form PGe4 tetrahedra that share corners with nine PCuGe3 tetrahedra and corners with three equivalent PCu3Ge trigonal pyramids. In the third P3- site, P3- is bonded to three equivalent Cu1+ and one Ge4+ atom to form PCu3Ge trigonal pyramids that share corners with six PCuGe3 tetrahedra and corners with six equivalent PCu3Ge trigonal pyramids.« less
