Title: Materials Data on MnCu2GeS4 by Materials Project

Abstract

Cu2MnGeS4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Mn2+ is bonded to four S2- atoms to form MnS4 tetrahedra that share corners with four equivalent GeS4 tetrahedra and corners with eight equivalent CuS4 tetrahedra. There are a spread of Mn–S bond distances ranging from 2.39–2.42 Å. Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four equivalent MnS4 tetrahedra, corners with four equivalent CuS4 tetrahedra, and corners with four equivalent GeS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.30–2.33 Å. Ge4+ is bonded to four S2- atoms to form GeS4 tetrahedra that share corners with four equivalent MnS4 tetrahedra and corners with eight equivalent CuS4 tetrahedra. There are three shorter (2.27 Å) and one longer (2.28 Å) Ge–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded to one Mn2+, two equivalent Cu1+, and one Ge4+ atom to form corner-sharing SMnCu2Ge tetrahedra. In the second S2- site, S2- is bonded to one Mn2+, two equivalent Cu1+, and one Ge4+ atom to form corner-sharing SMnCu2Ge tetrahedra. In the third S2- site, S2- is bonded to onemore » Mn2+, two equivalent Cu1+, and one Ge4+ atom to form corner-sharing SMnCu2Ge tetrahedra.« less
