| Popis: | A new dinuclear molybdenum(0) carbonyl complex with μ2-thiolato ligands [Et4N]2[Mo2(CO)7- (S,S-C6H4-1,2)] (1) has been synthesized by the reaction of tetraethylammonium benzene-1,2- dithiolate with molybdenum hexacarbonyl in acetonitrile, and characterized by routine elemental analysis and spectroscopy. The crystal and molecular structure of 1 has been determined by X-ray crystallography. Single crystals of 1 grown from a mixture solvent of acetonitrile and isopropanol crystallize in the orthogonal, space group Pnma (#62) with a = 31.081(5), b = 9.582(5), c = 11.557(6) A; V = 3441.9 A3; Z = 4; R1 = 0.045, R2 = 0.058. 1 possesses two thiolato- and one carbonyl-ligand bridges, and the MoS2Mo ring consisting of two SR bridges adopts the ‘butterfly’ conformation in syn-exo geometry with a MoMo bond distance of 2.9801(8) A, Mo SMo bond angle of 70.65(4)° and dihedral angle (between two MoSMo planes) of 96.54°. A cyclic voltammetry study indicated that 1 exhibited irreversible one-electron oxidation behavior which is very different from that observed in the complexes [Mo2(CO)8(SR)2]2− containing a planar MoS2Mo ring. |
