“…[6][7][8][9][10][11][12][13][14][15][16][17][18] These trinuclear and tetranuclear complexes are all optical limiters (σeff > σ0) with threshold-limiting fluence decreasing on proceeding from tetranuclear to trinuclear, and from W-containing to Mo containing clusters. Power limiting has also been found in Mo3(µ3-S)(µ2-S)3 cluster sulfides derivatized with maleonitrile dithiolate, oxalate and thiocyanate ligands, although no clear tendencies could be drawn upon ligand substitution.…”

“…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 three-dimensional adamantane-like nanoscopic cage built from four iodide-bridged triangular Mo3S7 cluster units

Chemical oxidation of a Mo 3 S 7 cluster featuring catecholate ligands, namely [Mo 3 S 7 (Cl 4 cat) 3 ] 2À (Cl 4 cat = tetrachlorocatecholate), allows the isolation of a unique nanoscopic molecular cage made of four iodide-bridged Mo 3 S 7 clusters as the kinetically favoured product.Metal-directed self-assembly is a versatile synthetic approach to produce discrete three dimensional polyhedral or cage compounds. Metal centers bring a variety of coordination sites and bond angles to a supramolecular framework, and in combination with different bridging ligands provide great versatility for chemical and structural modification of the inner cavity. 1 Recently, the use of multi-nuclear systems with labile positions (for example dimeric M 2 , where M = Mo, Rh) to build 3D supramolecular cages has also been explored, and new perspectives have been obtained on the facility for fine tuning the net charge, the magnetic properties and the electronic communication between the metal units. 2 In this context, the family of triangular [Mo 3 (m 3 -S)-(m-S 2 ) 3 X 6 ] 2À (X = halide) clusters are promising candidates as building blocks for multi-nuclear aggregates. This is due to the presence of two labile binding sites in a cis configuration (an X-Mo-X angle of ca. 901, see Scheme 1a), which can be easily occupied by a wide spectrum of ligands. In addition, ligand substitution in the [Mo 3 S 7 X 6 ] 2À dianion can be carried out selectively, affecting all six halide ligands or only the three halides cis to the m 3 -S sulfur atom, 3 demonstrating the geometry-guiding versatility of the metal centers (see Scheme 1b and c). Therefore, the Mo 3 S 7 cluster can be regarded as a tritopic building block to construct convex corners in tetrahedral symmetry-like supramolecular capsules or cages that enclose an isolated nanospace. 4 To date, all molecular architectures based on Mo 3 S 7 cluster entities possess 1 or 2D character (open structures), including the well known polymeric {M 3 S 7 X 2 X 4/2 } n solid phases (M = Mo, W), where each Mo 3 S 7 unit is covalently linked to its neighbors through four halide bridges forming zigzag chains. 5 Herein, we report the synthesis of a novel 3D cage based on a dodecanuclear Mo 12 complex adopting an adamantanoid structure built from four trinuclear Mo 3 S 7 entities bridged by six m-I atoms and encapsulating one iodide anion. This discrete cluster was first obtained as an unexpected product, but a detailed study has since revealed the experimental factors leading to its efficient self-assembly.In recent years, our research interests have focused on the coordination of redox-active ligands such as 1,2-dithiolenes to the trinuclear Mo 3 S 7 cluster, 6 to afford dianionic The molecular structure of (PPh 4 ) 3 [2] has been determined by X-ray diffraction methods.z The compound crystallizes in the acentric cubic space group P 43n and is comprised of dodecanuclear trianion units built from four Mo 3 S 7 trinuclear clusters (Fig. 1). The repeating metal core can be written as Mo 3 S 7 I 3 I 3/2...
