Abstract:	Racemic C₅H₅Mo(CO)₂LL]PF₆, (2) with LL = 2-benzoylpyridine-1-phenylethylimine, undergoes spontaneous resolution upon crystallization from acetone/CH₂Cl₂/ethanol. The absolute configuration of the (+)₅₄₆-isomer was shown to be (R) at the Mo atom and (R) at the asymmetric carbon atom. Comparison of 2 with C₅H₅Mo(CO)₂LL]PF₆ (1) (LL = 2-carbaldehydepyridine-1-phenylethylimine) reveals distinct changes caused by the differences resulting from the presence of the phenyl group in 2 and the change from the (RR)- to the (RS)-configuration.
