HPLC analysis shows that one isomer predominates in the product of nickel complex, while at least two main constitutional isomers exist in the product of other metal complexes. The complexes (in the form of mixture of constitutional isomers) were characterized by elemental analyses, MS, IR and UV-Vis spectroscopy.展开更多
