The complexes [ReCl(N2)(CNR){P(OMe)3}3](R = Me, Et, But, C6H4Me-4, or C6H4Cl;-4) and [ReCl(N2)(CNMe)(PPh3){P(OEt)3}2] have been prepared by reaction of the corresponding diazenido-species [ReCl2(NNCOPh)(PPh3)x{P(OR′)3}3–x](x= 0 or 1; R′= Me or Et) with the appropriate isocyanide in refluxing methanol, and the X-ray crystal structure of mer-[ReCl(N2)(CNMe){P(OMe)3}3] is reported. In these complexes the isocyanide ligand undergoes protic attack with cleavage of the unsaturated NC bond to afford the corresponding primary ammonium salt.
