Tetrayttrium(III) trisulfide disilicate, Y4S3(Si 27), crystallizes in the Sm4S3(Si 2O7) structure type. The structure consists of isolated (Si2O7)6- units (2mm. symmetry) and two crystallo-graphically independent Y3+ cations bridged by one S and one O atom. The first Y atom (site symmetry.m.) is coordinated by three O atoms and three S atoms in a trigonal-prismatic arrangement whereas the second Y atom (site symmetry..2) is coordinated by six O atoms and three S atoms in a tricapped trigonal-prismatic arrangement.
