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 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.
