The crystal structure described by Y4N2S3 crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent S(1), and two equivalent S(2) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to two equivalent N(1), one S(1), and three equivalent S(2) atoms. N(1) is bonded to two equivalent Y(1) and two equivalent Y(2) atoms to form NY4 tetrahedra that share corners with two equivalent S(1)Y6 octahedra, corners with two equivalent N(1)Y4 tetrahedra, corners with four equivalent S(2)Y5 trigonal bipyramids, edges with two equivalent S(1)Y6 octahedra,  an edgeedge with one N(1)Y4 tetrahedra, and edges with three equivalent S(2)Y5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 45°. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Y(2) and four equivalent Y(1) atoms to form SY6 octahedra that share corners with four equivalent N(1)Y4 tetrahedra, corners with ten equivalent S(2)Y5 trigonal bipyramids, edges with two equivalent S(1)Y6 octahedra, edges with four equivalent N(1)Y4 tetrahedra, and edges with two equivalent S(2)Y5 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Y(1) and three equivalent Y(2) atoms to form SY5 trigonal bipyramids that share corners with five equivalent S(1)Y6 octahedra, corners with four equivalent N(1)Y4 tetrahedra, corners with four equivalent S(2)Y5 trigonal bipyramids,  an edgeedge with one S(1)Y6 octahedra, edges with three equivalent N(1)Y4 tetrahedra, and edges with two equivalent S(2)Y5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 36-64°. is represented by the Crystallographic Information File (CIF) [CIF]
