Materials Data on CaLaGa3S7 by Materials Project
Abstract
CaLaGa3S7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ca–S bond distances ranging from 2.84–3.43 Å. La3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of La–S bond distances ranging from 2.87–3.37 Å. There are three inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four S2- atoms to form corner-sharing GaS4 tetrahedra. There are a spread of Ga–S bond distances ranging from 2.26–2.29 Å. In the second Ga3+ site, Ga3+ is bonded to four S2- atoms to form distorted corner-sharing GaS4 trigonal pyramids. There are a spread of Ga–S bond distances ranging from 2.22–2.32 Å. In the third Ga3+ site, Ga3+ is bonded to four S2- atoms to form corner-sharing GaS4 trigonal pyramids. There are a spread of Ga–S bond distances ranging from 2.22–2.31 Å. There are seven inequivalent S2- sites. In the first S2- site, S2- is bonded to two equivalent Ca2+, one La3+, and one Ga3+ atom to form distorted SCa2LaGa tetrahedra that share corners with six SCa2LaGa tetrahedra and edges with two SCaLa2Ga tetrahedra.
