本文报道了含乙烯和芳基膦配体的零价镍、钯和铂配合物（L= P（C6 H5）3，POC 6 H4 CH 3）3或P（m-C6 H4 CH 3）3）溶液的物理研究。ML 4复合物基本上解离成ML 3和L在25; thetPtL 4复合物，然而，被检测到的31 P核磁共振在-90。未检测到ML 3或（C2 H4）ML 2复合物的解离。报道了MLg+ C2 H4（C2 H4）ML 2 + L在25 ℃苯中的平衡常数，发现M= 1.25时为300、0.12和0.013。
Physical studies on solutions of zerovalent nickel, palladium, and platinum complexes containing ethylene and arylphosphine ligands (L= P (C6H5) 3, POC6H4CH3) 3, or P (m-C6H4CH3) 3) are reported. The ML4 complexes are substantially dissociated into ML3 and L at 25; thePtL4 complexes have, however, been detected by 31P nmr at—90. No dissociation of ML3 or (C2H4) ML2 complexes was detected. Equilibrium constants in benzene at 25 are reported for MLg+ C2H4(C2H4) ML2+ L and found to be 300, 0.12, and 0.013 for M=
