Crystal structure of penta-carbon-yl(2,2-di-fluoro-propane-thio-ato-κ)manganese(I).

The title compound, [Mn{SC(O)CFCH}(CO)], has been isolated as a by-product during the reaction of K[Mn(CO)] with CHCFCOCl. It is built up from a di-fluoro-methyl-propane-thio-ate bonded to an Mn(CO) moiety through the S atom. The Mn atom has an almost perfect octa-hedral coordination sphere. It is one of the rare examples of compounds containing the (CO)MnS-C fragment. In the crystal, the methyl group occupies a pocket surrounded by the O atoms of three carbonyl groups of the Mn(CO) moiety; however, the H⋯O distances are rather long. These inter-actions lead to the formation of layers lying parallel to (101), which enclose (15) and (16) ring motifs. The CF group is disordered over two sets of sites with occupancies of 0.849 (3) and 0.151 (3).
