ZINC-ORGANIC COMPOUNDS OF DIMETHYLGLYOXIME COORDINATED WITH Ni(Ⅱ), Pd(Ⅱ) AND Cu(Ⅱ) IONS

摘要

Coordinated oximes with Ni (Ⅱ), Pd (Ⅱ) and Cu (Ⅱ) ions proved capable of giving substitution reactions with a series of zincorganic compounds Studies made on the reaction products have revealed that in the case of dimethylglyoxime (further abbreviated DMGH_2) reaction products results from substitution O-H....O hydrogen bridges existing in such compounds, by O-Zn-O bridges. All compounds reported in this paper were separated from the reaction mixture as colored powders and were characterized by chemical analyses, IR spectroscopy, X-Ray diffraction spectra, proton NMR spectra and magnetic properties. The new zinc organic compounds form with amines adducts Among the amine adducts only the adducts with pyridine were isolated to confirm their formula and the binding manner.
