STUDY ON STRUCTURE OF SULFUR-BRIDGED TRANSITION METAL CLUSTERS——CRYSTAL AND MOLECULAR STRUCTURE OF (C_5H_7S_2)_3 [Mo_3(μ_3-S)_2 (μ_2-Cl)_3Cl_6]

The compound (C_5H_7S_2)_3[Mo_3 (μ_3--S)_2 (μ_2--Cl)_3 Cl_6] forms dark black octahedralcrystals with the following crystallographic parameters: a=22.885(10)A, c=25.407(7)A. Thespace group is I4_1/α, Z=16, ρ_(obs.)=2.073g/cm~3, ρ_(calc.)=2.126g/cm~3. The 1621 independentreflections with I≥3σ were collected on a CAD-4 four-circle diffractometer by means of MoK_αradiation. The structure was solved by three-dimensional Patterson synthesis and refined byleast squares technique to a final discrepancy factor of R=0.056. The results of our investiga-tion reveal that the molecule consists of a trinuclear Mo cluster anion and three planar mono-cations.surrounding the cluster anion. As the core of the anion the triad of Mo atoms, possessing anequilateral triangular configuration, is linked by two μ3--S bridging atoms and three μ2--Clatoms. Besides, two terminal Cl atoms are attached to each Mo atom to form an octahedralconfiguration. The diamagnetism and the short Mo-Mo distances (2.556 A, 2.641 A, 2.653 A)clearly indicate the existence of Mo-Mo bonds. The anion as a whole has an idealized D_(3h) localsymmetry.

SUBSTITUTION REACTION OF LIGANDS IN TRINUCLEAR Mo CLUSTERS WITH "LOOSE COORDINATION SITE" AS WELL AS SYN-THESIS AND CRYSTAL STRUCTURE OF Mo_3(μ_3-S) (μ-S)_3(dtp)_3(C_3H_4N_2)_3 (dtp)·(CH_3)_2CO

When trinuclear molybdenum cluster compound with "loose coordination site", Mo_3(μ_3-S)(μ-S)_3(μ-dtp)(dtp)_3·H_2O(A) (dtp=diethyldithiophos-phinato anion), is reacted with an excess of imidazole, the H_2O ligand and the bidentate bridging ligand μ-dtp are found to be simultaneously substituted by the imidazole to form the title compound. The title crystal belongs to the space group P(?), Z =2, with the following unit cell parameters: a=14.465(2), b=14.653(4), c=14.886(6), α=99.36(3),β=93.11(2),γ=114.29(2),V=2812(3). The crystalline compound consists of an ordered array of the cluster cation and dtp anion with acetone as packed molecule. The cation possesses a symmetry of C_3. Three Mo atoms form basically an equilateral triangle with three Mo—Mo bond lengths of 2.763 (1), 2.762(1), 2.756(1) respectively.

MOLYBDENUM-IRON MIXED METAL CLUSTERS (Ⅰ)——THE SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF (η~5-C_5H_5)_2Mo_2Fe_2(μ_4-Te)(μ_3-Te)_2(CO)_6

The reaction of Fe_2(μ_3-Te)_2(CO)_9 with Mo_2(CO)_6(η~5-C_5H_5) affords the title compound. Its X-ray analysis shows a butterfly structure for the Mo_2Fe_2 core; the two molybdenum atoms occupy the hinge with a Mo—Mo bond distance of 2.819 and the two iron atoms are on the tops of the wings with an average Mo—Fe bond distance of 2.932(2). Each molybdenum is bonded to a Cp ring, and three CO ligands are terminally bonded to each iron atom. One tellurium atom quadruply bridges Mo_Fe_2 with Mo—Te(μ_4)=2.625(2). and Fe—Te(μ_4)=2.713(2). Two tellurium atoms triply bridge the two triangular Mo_2Fe faces with Mo—Te(μ_3)=2.678(1) and Fe—Te(μ_3)=2.513(3). The molecule has C_(2v) symmetry and a bicapped triangle bipyramidal skeleton. Crystallographic parameters are as follows: space groupImm2(orthorhombic), a=14.562(3), b=10.391(1), c=7.139(4), V=1080.2(i)~3, Z=2, ρ(cald)=1.819g·cm~(-3). The final R factor was 2.2％ for 620 independent reflections(I>2σ(I)).
