The ligands α-mercaptobenzacetohydroxamic acid (MBAHA-H) and 2-amino-α-mercapto-benzacetohydroxamic acid (AMBAHA-H) and their different mixed ligand novel complexes with CrIII having specific formulae have been synthesized and characterised by elemental analyses, magnetic and conductance measurements, IR and electronic spectral studies. The ligands were found to behave as monobasic tridentate (SO’O donor) and tetradentate (SO’ ON donor) manner respectively. All the synthesized CrIII complexes were non-electrolyte with magnetic moment ranging from 3.79 to 3.87 BM. The structural assessment of the complexes has been carried out based on spectral studies (electronic&infrared) and molar conductivity values. All the complexes were found to be of octahedral geometry.
