Abstract: X-ray absorption fine structure (XAFS) at the K-edge of cobalt has been studied in some cobalt (II) mixed ligand complexes having hydroxamic acid as one of the ligands. The study can be used to yield useful and important information about the molecular structure of the complexes. The X-ray absorption measurements have been performed at the recently developed BL-8 Dispersive EXAFS beamline at 2.5 GeV Indus-2 Synchrotron Source at RRCAT, Indore, India. The data obtained has been processed using EXAFS data analysis program Athena. From the experimental measurements, the energies of the K absorption edge, chemical shifts, edge-widths, shifts of the principal absorption maximum in the complexes have been estimated. The data obtained from these studies have been utilized to estimate effective nuclear charge.
