Abstract
Addition of the aminothiolate HS(CH2)3NMe2 and potassium tert-butoxide to [{Ir(µ-Cl)(cod)}2](cod = cycloocta-1,5-diene) afforded the aminothiolate-bridged complex [{Ir[µ-S(CH2)3NMe2](cod)}2]1. This reacted with carbon monoxide to give the dinuclear tetracarbonyl complex [{Ir[µ-S(CH2)3NMe2](CO)2}2]2. The reaction of 1 with CO and phosphines or of 2 with phosphines provided the mixed-ligand complexes trans-[{Ir[µ-S(CH2)3NMe2](CO)(PR3)}2](R = C6H113, o-MeC6H44 or p-FC6H45). When the bulky phosphite P(OC6H4But-o)3 was used as phosphorus ligand the orthometallated complex trans-[{[graphic omitted]H3But-o)(OC6H4But-o)2]}2]6 was obtained. The crystal structures of 1 and 6, have been determined by X-ray diffraction methods.Keywords
