The Coordination Chemistry of 1,2-Bis[(diphenylphosphino)methyl]benzene with Nickel(II), Palladium(II), Platinum(II), and Platinum(0) and the X-Ray Crystals Structure of [Pt{1,2-bis[(diphenylphospino)methyl]benzene}(C2H4)]
1990
The preparation of complexes [MX2(1)] (M = Ni, Pd, and Pi; X - Cl, Br, and I; 1 = 1,2-bis[(diphenylphosphino)methyl]benzene). [Pt(OSO2CH3)Et(1)], [Pt(alkene)(1)] (alkene - C2H2, and CH2 = CHCN), and [(1)Pt-(μ-H)2PtH(1)][BPh4] is reported. Their 1H- and 31P-NMR spectra were recorded and used lor structural assignments. The X-ray crystal structure of [Pt(C2H4)(1)] was determined. It is shown that the PPtP 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.
