“…9 It is well-known that in [Mo3(µ3-S)(µ-S2)3] 4+ units the sulfur atoms that lie in the axial plane are slightly electrophilic, and consequently can interact with nucleophilic anions, such as the chloride/bromide ligands replaced by the diimine or dithiolene ligands during the substitution reaction.

Substitution of the halide ligands in (Bu4N)2[Mo3S7X6] (X = Cl, Br) by diimine ligands, such as 4,4'-dimethyl-2,2'-bipyridine (dmbpy), 2,2'-bipyridine (bpy) and 1,10-phenanthroline (phen), affords the neutral heteroleptic clusters Mo3S7Cl4(dmbpy) (1), Mo3S7Br4(dmbpy) (2), Mo3S7Br4(bpy) (3), and Mo3S7Br4(phen) (4). Further substitution of the halide ligands in Mo3S7Br4(diimine) clusters by dmit (1,3-dithiole-2-thione-4,5-dithiolate) allows the preparation of the mixed diimine-dithiolene neutral cluster complexes Mo3S7(dnbpy)(dmit)2 (5, dnbpy = 4,4'-dinonyl-2,2'-bipyridine), Mo3S7(dcmbpy)(dmit)2 (6, dcmbpy = 4,4′-dimethoxycarbonyl-2,2′-bipyridine), and Mo3S7(dcbpy)(dmit)2 (7, dcbpy = 2,2'-bipyridine-4,4'-dicarboxylic acid). The optical limiting properties of complexes 1 -7 have been assessed by the open-aperture Z-scan technique at 570 nm, employing a nanosecond optical parametric oscillator. In order to investigate the effect of increasing the -system, complexes 1 -4, with general formula Mo3S7X4(diimine), (X = Cl, Br), were compared to clusters 5 -7, containing the dmit ligand. The influence of the metal content on the optical power limiting properties was also investigated by comparing the trinuclear series of complexes prepared herein with the bis(dithiolene) dinuclear cluster (Et4N)2[Mo2O2S2(BPyDTS2)2], which has been recently prepared by our group. All trinuclear clusters 1 -7 are efficient optical limiters (eff > 0) with threshold limiting fluence F15% decreasing on proceeding from dinuclear to trinuclear clusters and, generally, on extending the -system.

A series of compounds containing the mononuclear complexes [M(tdci),13Ge, Sn) was prepared and characterized by elemental analysis, NMR spectroscopy, and FAB mass spectrometry. Characteristic fragmentation reactions in the mass spectra were elucidated. X-ray analysis of the Al"', Fe"', Ga"' , and In"' complexes revealed that two neutral, zwitterionic tdci ligands coordinate to the metal cation exclusively through deprotonated alkoxo groups.
