Organomanganese complexes with tin atoms in linear and trigonal-planar coordination environments are accessible by means of two different synthetic methods.Sequential treatment of the complex (η5-C5H4CH3)Mn(CO)2(THF (1a) with tin(II) chloride and zinc dust yields (μ3-Sn)5-C5H4CH3)Mn(CO)2>3 (2a); 2a is also formed from 1a and monostannane, SnH4.The pentamethylcyclopentadienyl derivative 1b yields analogously the two compounds (μ3-Sn)5-C5Me5)Mn(CO)2>3 (2b) and (μ-Sn)5-C5Me5)Mn(CO)2>2 (3b). 2a formally contains two Mn-Sn single bonds and a Mn-Sn double bond (X-ray diffraction study). - Keywords: Bridging tin atoms/ Organomanganese complexes

Photolysis of the manganese half-sandwich complex (η5-C5Me5)Mn(CO)3 (1) in tetrahydrofuran (THF) yields cleanly the solvent complex (η5-C5Me5)Mn(CO)2-THF (2).Compound 2 undergoes spontaneous elimination of carbon monoxide to give at ambient temperature in approx. 20 h, or upon removal of solvent in vacuo, the novel dinuclear derivative (η5-C5Me5)2Mn2(μ-CO)3 (3).Elemental analyses and infrared and mass as well as the 1H and 13C NMR spectra unequivocally demonstrate this compound to adopt a triply carbonyl-bridged structure containing the first example of a manganese-manganese multiple bond.
