Title: Materials Data on HfCrCuS4 by Materials Project

Abstract

HfCrCuS4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Hf4+ is bonded to six S2- atoms to form HfS6 octahedra that share corners with six equivalent CuS4 tetrahedra, edges with two equivalent HfS6 octahedra, and edges with four equivalent CrS6 octahedra. There are four shorter (2.54 Å) and two longer (2.55 Å) Hf–S bond lengths. Cr3+ is bonded to six S2- atoms to form CrS6 octahedra that share corners with six equivalent CuS4 tetrahedra, edges with two equivalent CrS6 octahedra, and edges with four equivalent HfS6 octahedra. There are two shorter (2.43 Å) and four longer (2.45 Å) Cr–S bond lengths. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with six equivalent HfS6 octahedra and corners with six equivalent CrS6 octahedra. The corner-sharing octahedra tilt angles range from 53–61°. There are two shorter (2.30 Å) and two longer (2.31 Å) Cu–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to two equivalent Hf4+, one Cr3+, and one Cu1+ atom. In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to onemore » Hf4+, two equivalent Cr3+, and one Cu1+ atom.« less
