Özet

A manganese(II) complex with novel coordination mode of picolinic acid (pic) has been synthesized and characterized by elemental analysis, magnetic susceptibility, FT-IR, thermal analysis (DTA and TG) and X-ray diffraction techniques. The complex crystallizes in the monoclinic space group P2(1)/c with unit cell parameters: a = 10.4086 (6), b = 0.9524 (6), c = 10.3570 (6) angstrom, beta = 107.904 (4)degrees and Z = 4. In the complex all donor sites of picolinato ligands participated to the coordination. The ring nitrogen and one of the carboxylate oxygen atom of picolinato ligand form chelate ring with one Mn2+ ion, whereas the other carboxylate oxygen atom is coordinated to the other Mn2+ ion and forming a polymeric structure thermally stable up to 338 degrees C.
