Interaction of Ni(II)with 2,3-dihydroxybenzoic acid

摘要

The reaction of NiCl_2 centre dot 6H_2O with 2,3-dihydroxybenzoic acid=L in n-PrOH:H_2O=1:1 solution,produced the complex {[Ni_5L_5(OH)_7]K_4 centre dot 13H_2O}_n.Its structure was investigated using elementalanalysis,IR,VU-Vis,NMR and ESMS spectroscopy.The complex is unstable in aqueous solution andits decpmposition scheme was proposed on the basis of NMR and ES MS specta.This may contribute to the understanding of oxidative degradation of catecholic derivatives by Ni(II),as well as to other similar ones.
