Abstract

BaCe(SnSe3)2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine Se2- atoms. There are a spread of Ba–Se bond distances ranging from 3.28–3.81 Å. In the second Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to nine Se2- atoms. There are a spread of Ba–Se bond distances ranging from 3.41–3.56 Å. There are two inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Ce–Se bond distances ranging from 2.97–3.15 Å. In the second Ce4+ site, Ce4+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Ce–Se bond distances ranging from 3.00–3.24 Å. There are four inequivalent Sn3+ sites. In the first Sn3+ site, Sn3+ is bonded in a 5-coordinate geometry to five Se2- atoms. There are a spread of Sn–Se bond distances ranging from 2.90–3.11 Å. In the second Sn3+ site, Sn3+ is bonded to six Se2- atoms to form edge-sharing SnSe6 octahedra. There are a spread of Sn–Se bond distances ranging from 2.74–2.85 Å.more »« less
