ThSbSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Th(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Se(1) atoms. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Th(1) and four equivalent Sb(1) atoms. Se(1) is bonded to five equivalent Th(1) atoms to form a mixture of distorted corner and edge-sharing SeTh5 trigonal bipyramids.
ThSbSe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Th(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Se(1) atoms. All Th(1)-Sb(1) bond lengths are 3.28 Å. There is one shorter (3.05 Å) and four longer (3.13 Å) Th(1)-Se(1) bond lengths. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Th(1) and four equivalent Sb(1) atoms. All Sb(1)-Sb(1) bond lengths are 3.04 Å. Se(1) is bonded to five equivalent Th(1) atoms to form a mixture of distorted corner and edge-sharing SeTh5 trigonal bipyramids.
