The synthesis and crystal structure of the cubane-like cluste with [Mo3CuS4] core is reported herein. The title compound crystallizes i triclinic space group Pl with the following unit cell dimensions: a 11.723(3), b = 14.353(6), c = 15.533(4)A;α= 75.40(3)°,β=69.13(2)°,γ 64.93(3)°; Z = 2; V = 2196 A3; DC = 2.033 g·cm-3.7704 independent reflec tions were collected on CAM four-circle diffractoneter with MoKa radiatio in the range of 1 < <25°, with only 2083 reflections having intensitie I > 3σ(I). The structure was determined by direct methods and refined b the least-squares method to a final R index of 0.091. There are some distortion in the cubane-like [Mo3CuS4] core, with three Mo-Mo bonds and thre weak Mo-Cu bonds.
