title: (eta5-cyclopentadienyl)(N,N-dimethyldithiocarbamato-kappa2S,S')[eta4-tetrakis(trifluoromethyl)cyclobutadienyl]molybdenum(IV).
abstract: The title complex, [Mo(C8F12)(C5H5)(C3H6NS2)], contains both a eta4-C4(CF3)4 cyclobutadienyl ligand with approximate C4v local symmetry and a eta5-C5H5 cyclopentadienyl ring. The centroids of the rings and the S atoms of a chelating dithiocarbamate ligand define the pseudo-tetrahedral coordination of the Mo atom. The Mo-C(cyclobutadienyl) bond lengths [2.189 (2)-2.211 (2) A] are unusually short, probably reflecting strong electron withdrawal by the trifluoromethyl groups. The molecules straddle crystallographic mirror planes.
