The material described by YbYCdS4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Yb(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Cd(1)S4 tetrahedra, edges with two equivalent Yb(1)S6 octahedra, and edges with four equivalent Y(1)S6 octahedra. Y(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form YS6 octahedra that share corners with six equivalent Cd(1)S4 tetrahedra, edges with two equivalent Y(1)S6 octahedra, and edges with four equivalent Yb(1)S6 octahedra. Cd(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form CdS4 tetrahedra that share corners with six equivalent Yb(1)S6 octahedra and corners with six equivalent Y(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 56-57°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to two equivalent Yb(1), one Y(1), and one Cd(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Yb(1), two equivalent Y(1), and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
