Coordination Chemistry of Perhalogenated Cyclopentadienes and Alkynes, X[1]. - Synthesis and Molecular Structure of a Cyclopentadienyl-1,3-dithiol Complex, [C5Cl3(SH)2]Mn(CO)3 The reaction of [C5Cl4Li]Mn(CO)3 with elemental sulfur leads to [C5Cl4SLi]Mn(CO)3 (1), which is easily oxidized by air to the disulfide (OC)3Mn[C5Cl4S-SCl4C5]Mn(CO)3 (2). Addition of one equivalent of BuLi, followed by an excess of S8 produces the dithiolate [C5Cl3(SLi)2]Mn(CO)3 (3), which yields the dithiol [C5Cl3(SH)2]Mn(CO)3 (5) upon hydrolysis. The molecular structures of 2 and 5 have been determined by X-ray diffraction
