Abstract

CdSnAs2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are six inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to four As3- atoms to form corner-sharing CdAs4 tetrahedra. There are three shorter (2.72 Å) and one longer (2.74 Å) Cd–As bond lengths. In the second Cd2+ site, Cd2+ is bonded to four As3- atoms to form CdAs4 trigonal pyramids that share corners with three equivalent CdAs4 tetrahedra, corners with three equivalent SnAs4 tetrahedra, and corners with six equivalent CdAs4 trigonal pyramids. There are a spread of Cd–As bond distances ranging from 2.66–2.86 Å. In the third Cd2+ site, Cd2+ is bonded to four As3- atoms to form corner-sharing CdAs4 tetrahedra. There are a spread of Cd–As bond distances ranging from 2.70–2.74 Å. In the fourth Cd2+ site, Cd2+ is bonded to four As3- atoms to form corner-sharing CdAs4 tetrahedra. There are three shorter (2.71 Å) and one longer (2.72 Å) Cd–As bond lengths. In the fifth Cd2+ site, Cd2+ is bonded to four As3- atoms to form corner-sharing CdAs4 tetrahedra.
