Effective Antifungal complexes of mixed lig ands with Calcium and zinc
Main Article Content
Abstract
Two new mixed ligand complexes of transition metals were manufactured by reaction of Zn(II) ion and Ca(II) ion with 2,2′-bipyridine as a primary ligand and L-valine as a secondary ligand. The ligands and their metal complexes were examined utilizing X-ray crystallography, ultravioletvisible spectra and Fourier-transform infrared spectroscopy. The mixed ligand complexes were described with formulae as Zn(Val)2(bipy.) and Ca(Val)2(bipy.). The metal complexes had a pseudo-octahedral structure, and both complexes have the same patterns of structure indicating crystal structure symmetry. However, the yield of Zn complex was at 50% of the basic materials and the yield of Ca complex was 81% of basic materials. Bioactivity showed that Ca chelate could suppressive Phytophthora.
