Abstract
CaSnO2 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 to six O2- atoms to form distorted CaO6 pentagonal pyramids that share corners with four equivalent CaO5 trigonal bipyramids, an edgeedge with one CaO5 trigonal bipyramid, and faces with two equivalent CaO6 pentagonal pyramids. There are a spread of Ca–O bond distances ranging from 2.35–2.56 Å. In the second Ca2+ site, Ca2+ is bonded to five O2- atoms to form distorted CaO5 trigonal bipyramids that share corners with four equivalent CaO6 pentagonal pyramids, an edgeedge with one CaO6 pentagonal pyramid, and edges with two equivalent CaO5 trigonal bipyramids. There are a spread of Ca–O bond distances ranging from 2.33–2.40 Å. There are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded in a T-shaped geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.06–2.43 Å. In the second Sn2+ site, Sn2+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Sn–O bond distances ranging from 2.10–2.39 Å. There are four inequivalent O2- sites. In the first O2-more »
