The preparation of complexes (M = Ni, Pd, and Pt; X = Cl, Br, and I; 1 = 1,2-bis<(diphenylphosphino)methyl>benzene), , (alkene = C2H4 and CH2 = CHCN), and <(1)Pt-(μ-H)2PtH(1)> is reported.Their 1H- and 31P-NMR spectra were recorded and used for structural assignments.The X-ray crystal structure of was determined.It is shown that the P-Pt-P bond angle in this complex differs significantly from those found in related compounds with monodentate phosphines, and that this difference is likely to be due to intramolecular contacts.
