- ItemA MISSING MEMBER OF THE PENTAMETHYLCYCLOPENTADIENYLIRIDIUM FAMILY - SYNTHESIS, REACTIVITY AND X-RAY CRYSTAL-STRUCTURE OF [(C5ME5IR)2(MU-CL)3]CLO4(1988) VALDERRAMA, M; SCOTTI, M; CAMPOS, P; SARIEGO, R; PETERS, K; VONSCHNERING, HG; WERNER, H
- Item[CP-ASTERISK-IR(P(O)(OME)2)3]-, AN IRIDIUM(III) PHOSPHONATE COMPLEX ACTING AS A CHELATING OXYGEN LIGAND - SYNTHESIS AND COORDINATION CHEMISTRY(1993) SCOTTI, M; VALDERRAMA, M; CAMPOS, P; KLAUI, WThe anionic iridium complex [(C5Me5)Ir{P(O)(OMe)2}3]- (L-) has been prepared as sodium salt from the corresponding trimethyl phosphite complex [(C5Me5)Ir{P(OMe)3}3](ClO4)2. L- reacts with metal ions M2+ to give ML2. With [PtMe3]2SO4 - 4H2O in water and with [{RhCl(cod)}2], cod = 1,5-cyclooctadiene, in cyclohexane solution the air-stable heterobimetallic complexes [LPtMe3] and [LRh(cod)] are formed. The rhodium complex [(C5Me5)Rh{P(O)(OMe)2}3]- (L'-) similarly gives [L'PtMe3] and [L'Rh(cod)]. [LRh(cod)] and [L'Rh(cod)] react with CO gas (1 atm.) to yield [LRh(CO)2] and [L'Rh(CO)2]. Partial decarbonylation of these dicarbonyl complexes at room temperature leads to the tetranuclear complexes [L'Rh(mu-CO)3RhL'](Rh-Rh) and [LRh(mu-CO)3RhL](Rh-Rh).
