Title: Materials Data on Ca(GaS2)2 by Materials Project

Abstract

CaGa2S4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (3.03 Å) and four longer (3.06 Å) Ca–S bond lengths. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (3.01 Å) and four longer (3.08 Å) Ca–S bond lengths. In the third Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ca–S bond distances ranging from 3.02–3.09 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing GaS4 tetrahedra. There are a spread of Ga–S bond distances ranging from 2.27–2.32 Å. In the second Ga3+ site, Ga3+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing GaS4 tetrahedra. There are one shorter (2.27 Å) and three longer (2.32 Å) Ga–S bond lengths. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometrymore » to two Ca2+ and two Ga3+ atoms. In the second S2- site, S2- is bonded to two Ca2+ and two Ga3+ atoms to form a mixture of distorted edge and corner-sharing SCa2Ga2 trigonal pyramids. In the third S2- site, S2- is bonded in a 4-coordinate geometry to two Ca2+ and two equivalent Ga3+ atoms. In the fourth S2- site, S2- is bonded in a 4-coordinate geometry to two Ca2+ and two equivalent Ga3+ atoms.« less
