Reaction of Mo(CO) 6 with p Cl C 6H 4SNa and Et 4NCl·H 2O in CH 3CN afforded a dinuclear molybdenum(0) compound 〔Et 4N〕 2〔Mo 2(CO) 8(SC 6H 4 Cl p ) 2〕 (1). The crystal structure was determined by X ray diffraction. The crystallographic data: C 36 H 48 Cl 2Mo 2N 2O 8S 2, M r = 963.71, monoclinic, P2 1/c, a=9.269(4), b=13.750(3), c=17.466(6) ;β=104.84(3)°; V=2151.8(3) 3; Z=2; D c =1^49 g/cm 3; F(000)=984; μ=8.3 cm -1 ; Mo Kα radiation ( λ =0.71073); Final R =0.055 and R w =0.065 for 3287 reflections with I>3.0σ(I ). The X ray structure analysis revealed that the Mo 2S 2 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 4.014(2) , and this obviously indicates the absence of Mo-Mo bond.
