Heteronuclear transition-metal complexes. Part I. Di-µ-organothio-(bis-π-cyclopentadienyltitanium)tetracarbonyl complexes of group VI, (π-C5H5)2Ti(SR)2M(CO)4

Abstract
Di-µ-organothio-(bis-π-cyclopentadienyltitanium)tetracarbonyls of Group VI, (π-C5H5)2Ti(SR)2M(CO)4(R = Me or Ph; M = Cr, Mo, or W), have been prepared by ligand-exchange reactions. Their i.r., 1H n.m.r., and electronic spectra provide evidence for appreciable metal–metal bonding.
