    Abstract:
    Analysis of 1H and 31P NMR of cis and trans isomers of {NiI2[(C6H11)2PH]2}, {NiBr2[(C6H11)2PH]2}, and of cis-{NiCl2[(C6H11)2PH]2} is reported. Assignment of coupling constants in these compounds as [AMY2]2, spin systems and use of these assignments (particularly 2JP-P′) in distinguishing cis and trans forms are discussed. The temperature dependence of the cis-trans equilibria of the bromide and iodide complexes, followed by the 31P spectra, is used to calculate thermodynamic constants for the isomerization. © 1980.
