Materials Data on CuS2 by Materials Project

Abstract

CuS2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Cu3+ is bonded to six equivalent S+1.50- atoms to form CuS6 octahedra that share corners with eight equivalent CuS6 octahedra, corners with six equivalent SCu3S tetrahedra, and edges with two equivalent CuS6 octahedra. The corner-sharing octahedral tilt angles are 64°. There are two shorter (2.45 Å) and four longer (2.47 Å) Cu–S bond lengths. S+1.50- is bonded to three equivalent Cu3+ and one S+1.50- atom to form SCu3S tetrahedra that share corners with three equivalent CuS6 octahedra, corners with thirteen equivalent SCu3S tetrahedra, and an edgeedge with one SCu3S tetrahedra. The corner-sharing octahedra tilt angles range from 69–73°. The S–S bond length is 2.04 Å.
