The crystal structure described by MnPb4Sb6S14 crystallizes in the monoclinic P2_1/c space group. Mn(1) is bonded to two equivalent S(7) and four equivalent S(1) atoms to form MnS6 octahedra that share corners with two equivalent Pb(2)S6 octahedra and edges with two equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles are 37°. There are two inequivalent Pb sites.
