•Synthesis and characterization of a hydrazone and its transition metal complexes.•Formation of unusual mixed ligand Zn (II) complex.•Cleavage study of the ligand at physiological pH.•All the tested compounds exhibited significant antihypertensive activity.
An unusual tetrahedral mixed ligand Zn(II) complex ZnT(L)Cl, where L = 2-chlorobenzaldehyde hydralazine hydrazone and T = in situ generated 3-(2-chlorophenyl)-1,2,4-triazolo[3,4-a]phthalazine is reported. Structure of the fused triazole has been confirmed by single crystal X-ray diffraction studies. Structure of Co(II), Ni(II), Cu(II) and Zn(II) complexes has been confirmed by spectral and analytical methods. Metal complexes have exhibited better activity in the fructose induced hypertension studies in animal model and are comparable with the standard.
