  • Abstract

    The nano and bulk structure polymer [Co(dipic)2Mn(O)2]n (where dipic is pyridine-2,6-dicarboxylic acid), was synthesized by sonochemical method and reflux process respectively. The bulk structure was characterized using single-crystal x-ray diffraction (SC-XRD). The crystal structure of this polymer, which was synthesized using a reflux approach, was found to be a binuclear coordination polymer. In this structure, the cobalt center achieves hexa-coordination by coordinating with two deprotonated dipicolinate groups, acting as tridentate chelating ligands. Manganese center achieves tetra-coordination with four -carboxylate oxygen from the dipic ligand of Co(dipic) 2-2. The nanostructure of this polymer was characterized using scanning electron microscopy (SEM), x-ray powder diffraction (XRD) and FT-IR spectroscopy and compared with bulk structure polymer.
