LaPS crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to four equivalent P(1), two equivalent S(2), and three equivalent S(1) atoms. In the second La site, La(2) is bonded in a 9-coordinate geometry to four equivalent P(1), two equivalent S(1), and three equivalent S(2) atoms. P(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent P(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent La(2) and three equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing SLa5 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent La(1) and three equivalent La(2) atoms to form a mixture of corner and edge-sharing SLa5 trigonal bipyramids.

In the first La site, La(1) is bonded in a 9-coordinate geometry to four equivalent P(1), two equivalent S(2), and three equivalent S(1) atoms. There are two shorter (3.28 Å) and two longer (3.34 Å) La(1)-P(1) bond lengths. Both La(1)-S(2) bond lengths are 2.91 Å. There is one shorter (2.99 Å) and two longer (3.01 Å) La(1)-S(1) bond lengths. In the second La site, La(2) is bonded in a 9-coordinate geometry to four equivalent P(1), two equivalent S(1), and three equivalent S(2) atoms. There are two shorter (3.02 Å) and two longer (3.29 Å) La(2)-P(1) bond lengths. Both La(2)-S(1) bond lengths are 2.90 Å. There are a spread of La(2)-S(2) bond distances ranging from 2.89-2.95 Å. P(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent P(1) atoms. There is one shorter (2.22 Å) and one longer (2.25 Å) P(1)-P(1) bond length. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent La(2) and three equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing SLa5 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent La(1) and three equivalent La(2) atoms to form a mixture of corner and edge-sharing SLa5 trigonal bipyramids.
