Abstract

A series of Cd(П), Zn(П), Ni(П), Hg(П), Cu(П) and Co(П) complexes with N′-(4-(dimethylamino)benzylidene)-2-oxo-2H-chromene-3-carbohydrazide (HAL) were synthesized in presence of SiO2 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, 1HNMR, 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.
