The betain-like SOC 2 (PPh 3 ) 2 (1a) reacts with [Mn 2 (CO) 10 ] in THF to produce the salt-like complex [(CO) 4 Mn(SOC 2 {PPh 3 } 2 ) 2 ][Mn(CO) 5 ] (2). 1a is bonded via the sulfur atoms which are arranged in trans position in the octahedral environment of the manganese atom. With InCl 3 from CH 2 Cl 2 solution the addition product [Cl 3 In(SOC 2 {PPh 3 } 2 )] (3) is obtained along with the salt (H 2 C{PPh 3 } 2 )[InCl 4 ] 2 (4), which is the result of proton abstraction from the solvent. The crystal structures of 2 · 0.5THF and 4 · CH 2 Cl 2 are reported. The compounds are further characterized by IR and 31 P NMR spectroscopy.
