Reaction of the thiobromide [Mo3S7Br6]2− cluster anion with 5,6-dimethyl-1,10-phenanthroline (Me2Phen) in solution leads to the substitution of two bromide ligands and the subsequent formation of a new mixed-ligand neutral complex [Mo3S7Br4(Me2Phen)] (I). Reaction of [Mo3S7Br6]2− with 5,6-dimethyl-1,10-phenanthroline in CH2Cl2 followed by treatment of I with Na(Dtc) · 3H2O (Dtc = diethyldithiocarbamate) results in the new mixed-ligand cluster complex [Mo3S7(Dtc)2(Me2Phen)]2+ (IIa). Slow evaporation of the CHCl3 solution of the complex in the presence of PF 6 − gives crystals of {[Mo3S7(Dtc)2(Me2Phen)]Br}PF6 · 3CHCl3 (II) characterized by X-ray structural analysis. Close contacts S...S result in the formation of cationic dimers {[Mo3S7(Dtc)2(Me2Phen)]2}4+ which form infinite chains through additional Sax...Br contacts. All compounds were characterized by IR, elemental analysis and ESI-MS. Synthesized complexes represent the first examples of heteroleptic Mo3S7 clusters containing phenanthroline ligands. [-]
