The material described by LaAsS crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 9-coordinate geometry to four equivalent As(1) and five equivalent S(1) atoms. As(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent As(1) atoms. S(1) is bonded to five equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing SLa5 trigonal bipyramids. is represented by the CIF file [CIF]
