Y(TiS2)2 crystallizes in the orthorhombic Imma space group. 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 Ti(2)S6 octahedra, edges with two equivalent Y(1)S6 octahedra, edges with two equivalent Ti(2)S6 octahedra, and edges with four equivalent Ti(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 4-5°. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form TiS6 octahedra that share edges with two equivalent Ti(1)S6 octahedra, edges with four equivalent Y(1)S6 octahedra, and edges with four equivalent Ti(2)S6 octahedra. In the second Ti site, Ti(2) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form TiS6 octahedra that share corners with six equivalent Y(1)S6 octahedra, edges with two equivalent Y(1)S6 octahedra, edges with two equivalent Ti(2)S6 octahedra, and edges with four equivalent Ti(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 4-5°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Y(1), one Ti(2), and two equivalent Ti(1) atoms. In the second S site, S(2) is bonded to two equivalent Y(1), one Ti(1), and two equivalent Ti(2) atoms to form a mixture of corner and edge-sharing SY2Ti3 square pyramids.
