Thermal and microbiological evaluation of Co(II), Ni(II), Cu(II), Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO₂ (IV) Complexes derived from thiazole Schiff base

A thiazole Schiff base has been prepared by the condensation of 2-hydroxy-5-chloro-3-nitro acetophenone and thiazole. The ligand was characterized by elemental analysis and spectral methods. The coordinating ability of the ligand is investigated by preparing its metal complexes with Co(II), Ni(II), Cu(II), Cr(III), Mn(III), Fe(III), VO(IV), Zr(IV) and UO2(VI) have been prepared and characterized by elemental analysis, molecular weight determinations, conductance measurements, spectral and thermal studies. All the complexes have been evaluated for their antimicrobial activity by agar cup-plate method against various organisms. The isolated products are coloured solids, soluble in DMF, DMSO and THF.
