LaSO crystallizes in the orthorhombic Cmce space group. La(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. S(1) is bonded to four equivalent La(1) and one S(1) atom to form distorted SLa4S trigonal bipyramids that share corners with twelve equivalent O(1)La4 tetrahedra, edges with two equivalent O(1)La4 tetrahedra, and edges with six equivalent S(1)La4S trigonal bipyramids. O(1) is bonded to four equivalent La(1) atoms to form OLa4 tetrahedra that share corners with four equivalent O(1)La4 tetrahedra, corners with twelve equivalent S(1)La4S trigonal bipyramids, edges with four equivalent O(1)La4 tetrahedra, and edges with two equivalent S(1)La4S trigonal bipyramids.
LaSO crystallizes in the orthorhombic Cmce space group. La(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. There are two shorter (3.17 Å) and two longer (3.18 Å) La(1)-S(1) bond lengths. There are two shorter (2.38 Å) and two longer (2.43 Å) La(1)-O(1) bond lengths. S(1) is bonded to four equivalent La(1) and one S(1) atom to form distorted SLa4S trigonal bipyramids that share corners with twelve equivalent O(1)La4 tetrahedra, edges with two equivalent O(1)La4 tetrahedra, and edges with six equivalent S(1)La4S trigonal bipyramids. The S(1)-S(1) bond length is 2.09 Å. O(1) is bonded to four equivalent La(1) atoms to form OLa4 tetrahedra that share corners with four equivalent O(1)La4 tetrahedra, corners with twelve equivalent S(1)La4S trigonal bipyramids, edges with four equivalent O(1)La4 tetrahedra, and edges with two equivalent S(1)La4S trigonal bipyramids.
