CaLa2S4 crystallizes in the tetragonal I-42d space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. La(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded to two equivalent Ca(1) and four equivalent La(1) atoms to form a mixture of distorted corner, edge, and face-sharing SCa2La4 octahedra. The corner-sharing octahedral tilt angles range from 17-50°.
CaLa2S4 crystallizes in the tetragonal I-42d space group. Ca(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are four shorter (2.88 Å) and four longer (3.15 Å) Ca(1)-S(1) bond lengths. La(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are a spread of La(1)-S(1) bond distances ranging from 2.89-3.17 Å. S(1) is bonded to two equivalent Ca(1) and four equivalent La(1) atoms to form a mixture of distorted corner, edge, and face-sharing SCa2La4 octahedra. The corner-sharing octahedral tilt angles range from 17-50°.
