phosphines R′2PCH2CH2PR′2 (R′ Me, dmpe; Et, depe; iPr, dipe) form the corresponding derivatives [NiR2(PP)]. Structures for the new compounds are proposed on the basis of IR and NMR (1H, 13C and 31P) studies and that of [Ni(CH2SiMe2Ph)2(dipe)] (2c) has been confirmed by an X-ray crystal structure investigation which shows the complex to be monoclinic, space group C2/c, with cell dimensions a = 16.947(7)
