Synthesis and structure of dimolybdenum(I) carbonyl compound with thiolateand carboxylate mixed-tri-bridging ligands [Bu4N] [Mo-2(CO)(6)(SC6H4Cl-p)(2)(CF3COO)]

The crystal of the title compound with formula C36H44Cl2F3Mo2NO8S2 (M-r = 1 0002.62) crystallized in monoclinic, space group P2(1)/n, with a = 9.6184(1 ), b = 22.3476(2), c = 20.7758(2) Angstrom, beta = 90.172(1)degrees, V = 44 65.70(7) Angstrom (3), Z = 4, D-c, = 1.491 g/cm(3), F(000) = 2032, mu = 0.8 33 mm(-1), Final R= 0.0665 and wR= 0.1650 for 5044 reflections with I>2.0 s igma (I). The crystal structure revealed that the Mo2S2 core is planar, and the trifluoroacetic group acts as a bidentate bridging ligand and coordina tes to two Mo atoms forming a five-membered ring plane, in which the Mo-Mo bond distance is 2.9222(9) Angstrom and the O-C-O angle is 131.8(7)degrees.
