Fe (III) complex with sterically constrained phenol based tetradentate N 2 O 2 ligand together with acetylacetone as ancillary ligand has been synthesized and characterized. Sterically constrained tetradentate ligand N,N'-dimethyl-N,N'-bis(2-hydroxy-3,5-dimethylbenzyl)-ethylenediamine (H 2 L) has been used here to synthesize mono nuclear octahedral mixed ligand Fe(III) complex 1. Characterization of this compound is carried out by electronic spectroscopy, ESI - MS and single crystal X-ray crystallography. Compound 1 crystalizes in monoclinic space group P 21/n with a = 8.43 A, b = 15.136 A, c = 21.105 A and z = 4. Antibacterial activity of complex 1 was performed by well plate technique. In the above experiment both Bacillus cereus and Escherichia coli were sensitive to the mononuclear mixed ligand complex [Fe III L(acac)] 1.
