Mg(MnS2)2 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Mg(1) is bonded to four equivalent S(1) atoms to form MgS4 tetrahedra that share corners with twelve equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 56-60°. Mn(1) is bonded to six equivalent S(1) atoms to form MnS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra and edges with six equivalent Mn(1)S6 octahedra. S(1) is bonded to one Mg(1) and three equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing SMgMn3 trigonal pyramids.

Mg(1) is bonded to four equivalent S(1) atoms to form MgS4 tetrahedra that share corners with twelve equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 56-60°. All Mg(1)-S(1) bond lengths are 2.45 Å. Mn(1) is bonded to six equivalent S(1) atoms to form MnS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra and edges with six equivalent Mn(1)S6 octahedra. There are four shorter (2.43 Å) and two longer (2.53 Å) Mn(1)-S(1) bond lengths. S(1) is bonded to one Mg(1) and three equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing SMgMn3 trigonal pyramids.
