Y(MnS2)2 is Spinel-like structured and 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 Mn(1)S4 tetrahedra, edges with two equivalent Y(1)S6 octahedra, and edges with four equivalent Mn(2)S6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form MnS4 tetrahedra that share corners with six equivalent Y(1)S6 octahedra and corners with six equivalent Mn(2)S6 octahedra. The corner-sharing octahedral tilt angles range from 51-65°. In the second Mn site, Mn(2) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form MnS6 octahedra that share corners with six equivalent Mn(1)S4 tetrahedra, edges with two equivalent Mn(2)S6 octahedra, and edges with four equivalent Y(1)S6 octahedra. 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 Mn(1), and two equivalent Mn(2) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Y(1), one Mn(1), and one Mn(2) atom.
