摘要: Abstract New complexes of the type cis -[MX 2 (PP′)] (M= Ni, Pd and Pt; X=Cl, Br, I or NCS PP′=( m - FC 6 H 4 ) PCH CH PPh ( p -FC have been synthesized characterized on basis 31 P{ 1 H}NMR NMR, IR UV spectroscopy, elemental analysis magnetic susceptibility measurements. All these are found to be low spin, diamagnetic square planar. H} spectra exhibit extraordinarily large downfield coordination chemical shifts, J P P′) 195 pt P) couplings discussed. Ring contribution (ΔR) values for palladium platinum calculated from P NMR data.
