Ca(MnS2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Ca(1) is bonded to four equivalent S(1) atoms to form CaS4 tetrahedra that share corners with twelve equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 53-65°. Mn(1) is bonded to six equivalent S(1) atoms to form distorted MnS6 octahedra that share corners with six equivalent Ca(1)S4 tetrahedra and edges with six equivalent Mn(1)S6 octahedra. S(1) is bonded to one Ca(1) and three equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing SCaMn3 tetrahedra.

Ca(1) is bonded to four equivalent S(1) atoms to form CaS4 tetrahedra that share corners with twelve equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 53-65°. All Ca(1)-S(1) bond lengths are 2.68 Å. Mn(1) is bonded to six equivalent S(1) atoms to form distorted MnS6 octahedra that share corners with six equivalent Ca(1)S4 tetrahedra and edges with six equivalent Mn(1)S6 octahedra. There are four shorter (2.36 Å) and two longer (2.90 Å) Mn(1)-S(1) bond lengths. S(1) is bonded to one Ca(1) and three equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing SCaMn3 tetrahedra.
