Materials Data on Li3CuS2 by Materials Project

Abstract

Li3CuS2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing LiS4 tetrahedra. There are two shorter (2.44 Å) and two longer (2.48 Å) Li–S bond lengths. In the second Li1+ site, Li1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing LiS4 tetrahedra. All Li–S bond lengths are 2.49 Å. Cu1+ is bonded in a linear geometry to two equivalent S2- atoms. Both Cu–S bond lengths are 2.17 Å. S2- is bonded to six Li1+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing SLi6Cu pentagonal bipyramids.
