The reaction of Mo(CO)6 with m-CH_3-C6H4SNa and Et4NCl(H_2O in CH_3CN afforded a dinuclear molybdenum(0) compound [Et4N]2[Mo2(CO)8(SC6H4-CH_3-m)2] (1). The crystal structure was determined by X-ray crystallography. The crystallographic data: C38H54Mo2N2O8S2, Mr = 922.87, triclinic, P_ 1, a =10.336(2), b=10.753(2), c=11.121(2) ?, ( =88.88(2), ( =68.64(1), ( =69.71(1)(, V=1071.5(1) ?3, Z=1, Dc=1.43 g/cm3, F(000) = 476, ( = 7.1cm－1, Final R = 0.036 and Rw = 0.045 for 3423 reflections with I >3.0( (I). The X-ray structure analysis revealed that the Mo2S2 core is planar. The geometry around each Mo atom is a distorted octahedron, both of which form an edge-sharing bioctahedron. The Mo...Mo distance is 4.0665(1)(, which obviously indicates the absence of Mo-Mo bond.
