| Abstract: | Reaction of Mo (CO)6 with p-Cl-C6H4SNa and Et4NCl · H2O in CH3CN afforded a dinuclear molybdenum (0) compound [Et4N]2 [Mo2 (CO)8 (SC6H4-Cl-p)2] (1). The crystal structure was determined by X-ray diffraction. The crystallographic data: C36H48Cl2Mo2N2O8S2, Mr= 963.71, monoclinie, P21/c, a=9. 269(4),b=13.750(3), c=17.466(6) A ;β=104.84(3)°; V=2151.8(3) A3; Z=2; Dc=1.49 g/cm3; F(000)=984; μ=8.3 cm-1; MoKα radiation (λ=0. 71073A ); Final R = 0. 055 and Rw=0. 065 for 3287 reflections with I＞3. 0σ(I). The X-ray structure analysis revealed that the Mo2S2 core is planar. The geometry around each Mo atom is a distance is 4. 014(2) A , and this obviously indicates the absence of Mo-Mo bond. |
