Materials Data on Ce10S19 by Materials Project
Ce10S19 crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. there are three inequivalent Ce+3.80+ sites. In the first Ce+3.80+ site, Ce+3.80+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Ce–S bond distances ranging from 2.87–2.98 Å. In the second Ce+3.80+ site, Ce+3.80+ is bonded in a 9-coordinate geometry to nine S2- atoms. There are a spread of Ce–S bond distances ranging from 2.88–3.14 Å. In the third Ce+3.80+ site, Ce+3.80+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ce–S bond distances ranging from 2.84–3.09 Å. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to four equivalent Ce+3.80+ atoms. In the second S2- site, S2- is bonded to five Ce+3.80+ atoms to form a mixture of distorted edge and corner-sharing SCe5 trigonal bipyramids. In the third S2- site, S2- is bonded to five Ce+3.80+ atoms to form a mixture of distorted edge and corner-sharing SCe5 trigonal bipyramids. In the fourth S2- site, S2- is bonded in a 5-coordinate geometry to four Ce+3.80+ and one S2- atom. The S–S bond length is 2.18 Å. In the fifth S2- site, S2- is bonded to five Ce+3.80+ atoms to form a mixture of distorted edge and corner-sharing SCe5 trigonal bipyramids. In the sixth S2- site, S2- is bonded in a 5-coordinate geometry to four Ce+3.80+ and one S2- atom.
