YPS crystallizes in the orthorhombic Pnma space group. There are two inequivalent Y sites. In the first Y site, Y(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 Y site, Y(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 distorted hexagonal planar geometry to two equivalent Y(1), two equivalent Y(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 Y(2) and three equivalent Y(1) atoms to form a mixture of distorted edge and corner-sharing SY5 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Y(1) and three equivalent Y(2) atoms to form a mixture of distorted edge and corner-sharing SY5 trigonal bipyramids.

In the first Y site, Y(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 (3.11 Å) and two longer (3.13 Å) Y(1)-P(1) bond lengths. Both Y(1)-S(2) bond lengths are 2.77 Å. There are a spread of Y(1)-S(1) bond distances ranging from 2.81-2.90 Å. In the second Y site, Y(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 (2.91 Å) and two longer (3.11 Å) Y(2)-P(1) bond lengths. Both Y(2)-S(1) bond lengths are 2.76 Å. There are a spread of Y(2)-S(2) bond distances ranging from 2.74-2.83 Å. P(1) is bonded in a distorted hexagonal planar geometry to two equivalent Y(1), two equivalent Y(2), and two equivalent P(1) atoms. There is one shorter (2.23 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 Y(2) and three equivalent Y(1) atoms to form a mixture of distorted edge and corner-sharing SY5 trigonal bipyramids.
