Structure of bis(tetraphenylphosphonium) tris[chlorocopper(I)]tetrathiomolybdate(VI) methyl cyanide solvate, [Ph4P]2[MoS4(CuCl)3].CH3CN

Solvothermal Synthesis of a New Mixed-Metal Polysulfide Cluster, [Me4N]3[MoS4Cu3(S5)2]

“…The tetrathiometallate moiety acts as a tetradentate bridging ligand toward three copper(I) atoms with Mo···Cu distances of 2.799(1) and 2.648(1) Å, which are longer than those of 2.615(2) and 2.621(1) Å in [MoS 4 (CuCl) 3 ] 2- . It is notable that the Cu(1)···Mo(1) distance of 2.799(1) Å is over 0.1 Å longer than the corresponding distance in [MoS 4 (CuX) n ] 2- . , The Cu(1)−S(1) bond of 2.344(2) Å is significantly longer than that (2.240(2) Å) in [MoS 4 (CuCl) 3 ] 2- .

“…The oxidation states of the metal atoms were checked by the bond valence method, which yielded bond valence sums of 5.69, 1.18, and 1.08 for Mo(1), Cu(1), and Cu(2), respectively . The MoS 4 Cu 3 core in this tetranuclear cluster is similar to that in [MoS 4 (CuCl) 3 ] 2- …”

In several derivatives [49,56,77,93,119,120,143] two crystallographically independent molecules are present in the same crystal, and in two cases [41,76] Table 11, where several relationships, as discussed individually in each chapter, may be observed. The M-M bond lengths are summarised in Table 12, where the variety of metals which can interact with the soft copper(I) atom can be seen.…”

“…The second type of structure contains mostly those examples with three copper(I) atoms, with the fourth metal being either tungsten, molybdenum or vanadium[42,[76][77][78][79][80] (Table 4B) . The…”
