The new compound SnSb₄S₇ has been synthesized at 600°C by reacting simple sulfides of Sn and Sb. It crystallizes in the monoclinic system, space group P2₁/m, with a 11.331(10), b 3.865(2), c 13.940(5) Å, β 105.281(6)°, V 588.9(4) ų and Z = 2. The crystal structure has been refined to R₁ = 5.18% for 1331 unique [F₀ > 4σ(F₀)] reflections collected on a Bruker single-crystal diffractometer with a CCD detector and monochromated MoKα X-radiation. The structure consists of rods of Sb₄S₆ and Sn₂Sb₄S₈ organized into a configuration that represents the first monoclinic member of the meneghinite homologous series, Me²⁺_2N–4Me³⁺₄S_2N+2, with N_1,2 = 2, 3, i.e., N_ave = 2.5. Partial miscibility of Sn and Sb in some positions of the larger rods is observed in this sulfosalt.
