Abstract: The title compound, (C₈H₂₀N)₂[Cu₂Mo₂(C₂H₄S₂)₂(CN)₂S₄], is a sulfide-bridged tetranuclear complex in which the complex anion comprises one [(edt)₂Mo₂S₂(-S)₂]^2- unit (edt = ethanedithiolate) and two CuCN units joined through six Cu-₃-S bonds, thus forming a cubane-like [Mo₂S₄Cu₂] core. There are two independent cation-anion complex entities in the asymmetric unit. Bond distances are normal for this type of complex [ranges: Mo-S = 2.193 (2)-2.390 (2); Cu-S = 2.266 (2)-2.470 (2); Cu-C = 1.899 (7)-1.911 (9) Å]. One of the thiolato C atoms is disordered over two sites in a 0.52 (3):0.48 (3) ratio.
