Abstract
A series of Cd(n), Zn(n), Ni(n), Hg(n), Cu(n) and Co(n) complexes withN '-(4-(dimethylamino)benzylidene)-2-oxo-2H-chromene-3-carbohydrazide (HAL) were synthesized in presence of SiO(2)as a catalyst that consumed time of the reaction and produced high yield. The building formula of prepared compounds was verified by using various performances like (IR, UV-Visible,(HNMR)-H-1, SEM, XRD, ESR, MS, thermal analysis, elemental analysis & magnetic measurements). The optimized structure of all prepared compounds was proved by applying DFT theory. Also, MIC and the colorimetric assay for isolated solid compounds were tested.
