Bis(di–isopropylamino)phosphido and di-isopropylaminophosphinidene metal carbonyl complexes from reactions of manganese and cobalt carbonyls with bis(di-isopropylamino)phosphine: X-ray crystal structures of (Pri2N)2PMn2(CO)8H and Pri2NPCo3(CO)9

Abstract

Reactions of (Prⁱ₂N)₂PH with Mn₂(CO)₁₀(photochemical in tetrahydrofuran) and Co₂(CO)₈(hexane at ambient temparature) give yellow (Prⁱ₂N)₂PMn₂(CO)₈H and green-black Prⁱ₂NPCo₃(CO)₉, respectively, whose structures have been determined by X-ray crystallography; reaction of (Prⁱ₂N)₂PMn₂(CO)₈H with HX (X = CL and Br) results in cleavage of a P–N bond but retention of the Mn–H bond to give (Prⁱ₂NPX)Mn₂(CO)₈H.
