ABSTRACT:
The reaction of benzene-1,3-diol with ethyl cyanide have been studied and the product 1-(2,4-dihydroxyphenyl)ethanone have been isolated. Divalent metal complexes of Co(II), Ni(II), Zn(II) and Pd(II) have been synthesized and tentative structures were proposed for these complexes based on elemental analysis, electrical conductivity, UV-Vis, IR, 1HNMR, 13CNMR.The spectra studies suggested bidentate co-ordination through the carbonyl and deprotonated hydroxyl group. The formula determination by method of continuous variation suggested a metal:ligand ratio of 1:2. A tetrahedal geometry has been suggested for the complexes.
KEYWORDS:
Ligands; complexes; spectra; tetrahedral geometry.
