测定了环戊基(苯)膦-镍(II), 钯(II)和铂(II)十五种配合物的可见-紫外光谱, 并参照各吸收谱带的归宿, 推断了配合物的空间构型及其在溶液中的构型异构化现象.

Visible and UV absorption spectra of fifteen complexes oc cyclopentyl(phenyl)phosphine-Ni(II), Pd(II), and Pt(II) were reported and their steric-configurations were deduced preliminarily. Moreover, mutual transformation of stereo-configurations of Ni(II)-complexes in solns. was discussed. Owing to the steric effect of the substituents in the phosphines, the Ni(II) complexes of cyclopentyl(phenyl)phosphines containing Ph group show the existence of tetrahedral configuration in solution
