Materials Data on CaSn2S5 by Materials Project
Abstract
CaSn2S5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.87–3.26 Å. In the second 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 2.84–3.49 Å. There are five inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six S2- atoms to form SnS6 octahedra that share corners with two equivalent SnS6 octahedra and corners with four SnS4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. There are two shorter (2.52 Å) and four longer (2.63 Å) Sn–S bond lengths. In the second Sn4+ site, Sn4+ is bonded to six S2- atoms to form SnS6 octahedra that share corners with two equivalent SnS6 octahedra and corners with four SnS4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Sn–S bond distances ranging from 2.54–2.62 Å. In the third Sn4+ site, Sn4+ is bonded to six S2- atoms to form SnS6 octahedra that share corners withmore »
