The heat capacity of molybdenum chalcogenides with different Sn/Ga content was measured at temperatures of T ≤ 60 K. The occurrence of two phases of the chalcogenides studied could clearly be seen for higher Ga concentrations. In the miscibility gap there coexists a superconducting phase (T c= 12.5 K) SnGa0.25Mo5S6 with the ferromagnetic GaMo5S6 phase (T curie = 19 K). As for the pure ternary compound GaMo5S6, a singularity of the heat capacity could also be observed in the range of the structural change (T = 45 K). All the singularities are discussed.
