Materials Data on LuZnCuAs2 by Materials Project
Abstract
LuCuZnAs2 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Lu3+ is bonded to six As3- atoms to form LuAs6 octahedra that share corners with six equivalent CuAs4 tetrahedra, corners with six equivalent ZnAs4 tetrahedra, edges with six equivalent LuAs6 octahedra, edges with three equivalent CuAs4 tetrahedra, and edges with three equivalent ZnAs4 tetrahedra. There are three shorter (2.81 Å) and three longer (2.94 Å) Lu–As bond lengths. Cu1+ is bonded to four As3- atoms to form CuAs4 tetrahedra that share corners with six equivalent LuAs6 octahedra, corners with six equivalent CuAs4 tetrahedra, edges with three equivalent LuAs6 octahedra, and edges with three equivalent ZnAs4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–53°. There are three shorter (2.49 Å) and one longer (2.60 Å) Cu–As bond lengths. Zn2+ is bonded to four As3- atoms to form ZnAs4 tetrahedra that share corners with six equivalent LuAs6 octahedra, corners with six equivalent ZnAs4 tetrahedra, edges with three equivalent LuAs6 octahedra, and edges with three equivalent CuAs4 tetrahedra. The corner-sharing octahedra tilt angles range from 16–57°. There are one shorter (2.51 Å) and three longer (2.52 Å) Zn–As bond lengths. There are two inequivalent As3- sites. In the first As3-more »
