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)]

Abstract

Abstract The preparation of complexes [MX 2 ( 1 )] (M = Ni, Pd, and Pi; X ‐ Cl, Br, and I; 1 = 1,2‐bis[(diphenylphosphino)methyl]benzene). [Pt(OSO 2 CH 3 )Et( 1 )], [Pt(alkene)( 1 )] (alkene ‐ C 2 H 2 , and CH 2 = CHCN), and [( 1 )Pt‐(μ‐H) 2 PtH( 1 )][BPh 4 ] is reported. Their 1 H‐ and 31 P‐NMR spectra were recorded and used lor structural assignments. The X‐ray crystal structure of [Pt(C 2 H 4 )( 1 )] 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.
