Materials Data on Zn4Ga2S7 by Materials Project
Abstract
Zn4Ga2S7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are four inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Zn–S bond distances ranging from 2.42–3.04 Å. In the second Zn2+ site, Zn2+ is bonded to four S2- atoms to form ZnS4 trigonal pyramids that share corners with three equivalent GaS4 tetrahedra and an edgeedge with one GaS4 tetrahedra. There are a spread of Zn–S bond distances ranging from 2.35–2.42 Å. In the third Zn2+ site, Zn2+ is bonded to five S2- atoms to form distorted ZnS5 trigonal bipyramids that share corners with three GaS4 tetrahedra, an edgeedge with one GaS4 tetrahedra, and edges with two equivalent ZnS5 trigonal bipyramids. There are a spread of Zn–S bond distances ranging from 2.48–3.01 Å. In the fourth Zn2+ site, Zn2+ is bonded in a bent 150 degrees geometry to two S2- atoms. There are one shorter (2.14 Å) and one longer (2.16 Å) Zn–S bond lengths. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four S2- atoms to form distorted GaS4 tetrahedra that share a cornercornermore »
