Reaction of the cluster salt [(eta(5)-Cp')(3)Mo3S4][pts] ([1][pts], Cp' = methylcyclopentadienyl; pts = p-toluenesulfonate) with CuCl yielded a new heterobimetallic cluster, [(eta(5)-Cp')(3)Mo3S4Cu(Cl)][pts] ([2][pts]). X-ray crystal structure determination of [1][pts] and [2][pts] showed that the incorporation of CuCl into the Mo3S4 cluster core has only minor consequences on the Mo-Mo and Mo-S distances. The metal atoms in the cluster core of [2](+) form an almost regular tetrahedron. The [2](+) cation conforms to an idealized C-3nu symmetry ignoring the Cp' groups since the Cu-Cl bond is almost aligned with the axis defined by the Cu-S(4) cube diagonal.
