A series of complexes of the type [M(EHPQH)2X2] where M = Co(II), Ni(II) and Cu(II), EHPQH=2-ethyl, [3(hydroxypropyl)]-3, 1 4H quinazoline -4-hydrazone, X= Cl- , Br- , I- and No-3 - . The geometry of the complexes have been elucidated in the light of molar mass, elemental analysis, IR, electronic Spectra, molar conductance and magnetic susceptibility. The measured molar conductance value indicates that the complexes are non-electrolytic in nature. The above observation indicates that Schiff bases EHPQH behave as bidentate ligand and coordination proposes through azomethine N and oxygen atom of alcoholic group of ligand. The remaining coordination sites are satisfied by negative ion such as Ci- , Br- , I- and NB- . The geometry of the Co(II) and Ni(II) were proposed to be octahedral in geometry whereas Cu(II) complexes were proposed to be distorted octahedral. The Schiff bases and its complexes have been evaluated for their antibacterial activity. The complexes show enhanced antibacterial activity than ligand.
