Abstract
Treatment of (CH3CN)3Mo(CO)3 with the trimetaphosphate salt [PPN]3[P3O9]·H2O([PPN]+=[Ph3PN-PPh3]+) (acetonitrile, 25°C) gave the trimetaphosphate-molybdenum complex [(P3O9)Mo(CO)3]3- in 91% isolated yield. [PPN]3[(P3O9)Mo(CO)3] was also obtained in 77% isolated yield by directly treating Mo(CO)6 with [PPN]3[P3O9]·H2O in refluxing acetonitrile, presumably by generating (CH3CN)3Mo(CO)3in situ. Reported herein is the full characterization and structural determination of [PPN]3[(P3O9)Mo(CO)3]and comparison to synthesized and calculated [(P3O9)M(CO)3]n- (M=group 6–9) complexes.
