“…[18][19][20][21][22][23][24][25] Intracluster metal-metal and metal-sulfur bond distances are consistent with those for an oxidation state of +4 for the metal, and the presence of single metal-metal bonds (see Table 1).

“…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.

“…The Cp 2 Mo(L) 2 complexes have two Mo(IV)-S bonds whereas the [Cp 2 Mo(thionucleobase)]Cl complexes contain one Mo(IV)-S and one Mo(IV)-N bonds in the ancillary positions. The Mo(IV)-S bond is more inert than Mo(IV)-N bond [47]. Since in the Cp 2 Mo(L) 2 complexes (L = glutathione, S-4-thio-2,3,4,6-tetrafluorobenzoic acid, S-1-thio-β-D-glucose and S-1-thio-2,3,4,5-tetracaetic β-D-glucose) both ancillary ligands involve thiolate coordination, the availability of vacant sites at this position is non-existent.…”

In contrast, in the [Cp 2 Mo(thionucleobase)]Cl complexes, the Mo(IV)-N bond is more labile than Mo(IV)-S bond [47] and the hydrolysis of this bond allow one vacant site on the Mo(IV) center to further react with important biomolecules and express antiproliferative activity.…”

“…While based on thermodynamic considerations, the Mo(IV)-O bond strength in Cp 2 Mo 2+ is stronger than Mo(IV)-S [48,49], the Mo(IV)-O bond is more labile [47]. Thus, the objective of these two compounds (Cp 2 Mo(malonate) and [Cp 2 Mo(maltolato)]Cl) was also to elucidate the role of the oxygen chelating ligands, the aqueous stability and charge on the molybdenocene cytotoxic activity.…”

The potential application of metallocene complexes into the cancer research was established by the pioneer work of Köpf-Maeir and Köpf in the late 1970s. The combination of organometallic chemistry and biochemistry created a new research area: bioorganometallic chemistry. Bioorganometallic chemistry has developed rapidly in the last thirty years leading to application of organometallic species into diagnostic, sensors, immunoassays and anticancer research among others. This review focuses on the bioorganometallic chemistry of molybdenocene dichloride and its derivatives as metal-based anticancer drugs. The anticancer properties of molybdenocene dichloride and its derivatives are described as well as the mechanism of action, aqueous and coordination chemistry, and molybdenocene-biomolecule interactions.

Reaction of [Mo3Y(mu-S)3(dtp)4(H2O)] (Y = O, S; dtp = S2P(OC2H5)2(-)) with HgI2 gave the novel compound [[Mo3S7(dtp)3]4 x I][(HgI3)3] x 4H2O (1), which contains a [[Mo3S7(dtp)3]4 x I] tetramer and (HgI3)-. Compound 1 has been characterized by IR, Raman, UV/Vis, and NMR spectroscopy and single-crystal X-ray diffraction analysis. It is shown that this formation process can be referred to as a new cluster reaction. The structure and spectroscopic data of the tetramer is also compared with that of the related discrete cluster [Mo3S7(dtp)3 x I]. Crystal data: space group F23, a = 26.786(3) A, V = 19218.7(4) A3, Z = 4, R = 0.059.
