From a theor. anal. of the absorption spectral data of Ni2+ ion in Ni(BiquO2)3X2, as measured by A. Seminara et al. (1984) it is proposed that in [Ni(BiquO2)3]2+ complex, the 2 2,2'-biquinoline N,N'-dioxide ligands occupy the trigonal distorted D3 symmetry sites with the Ni2+ ion locates in the center. The complete absorption spectrum of Ni2+ ions in [Ni(BiquO2)3]2+ complexes was calculated The effective magnetic moment of Ni2+ ion and crystal field splitting was determine A good agreement between the theor. and observed values was observed

Key words: ABSORPTION SPECTROMETRY, OXIDE, COUPLING CONSTANT, STERIC EFFECT, STEREOCHEMISTRY, MOLECULAR ORBITAL THEORY, NICKEL COMPLEX, QUINOLINE P, CONFIGURATION, MAGNETIC MOMENTS
