摘要：

The reactions of the dialkyls [NiR2(tmed)] (R=CH2C6H4-o-Me or CH2SiMe2Ph; tmed=N,N,N',N'-tetramethylethyl-enediamine) with the chelating phosphines R'2PCH2CH2PR'2 (R'= Me, dmpe; Et, depe; (i)Pr, dipe) form the corresponding derivatives [NiR2(P-P)]. Structures for the new compounds are proposed on the basis of IR and NMR (H-1, C-13 and P-31) 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), b = 19.011(7), c = 11.082(3) angstrom, beta = 100.93(2)-degrees, V= 2299.1 angstrom3 and Z = 4.
