Abstract

The title complex, [Co(pypr)(2)(sac)(2)] (pypr = 2-pyridinepropanol and sac = saccharinate). has been prepared and characterized by elemental analysis, electronic and FTIR spectra, magnetic susceptibility measurements, thermal analysis and X-ray diffractometry. The complex crystallizes in triclinic space group P (1) over bar with a=8.1836(2), b=10.0062(2), c=10.4989(3)Angstrom, alpha=90.474(1), beta=107.989(1) and gamma=110.923(1)degrees. The cobalt(II) ion sits on a center of symmetry and is octahedrally coordinated by two pypr and two sac ligands. Both pypr and sac ligands occupy the trans positions of the coordination octahedron. The two pypr ligands are neutral and act as bidentate N- and O-donor ligands forming two symmetry-related seven-membered chelate rings around the cobalt(II) ion, while both sac ligands are O-coordinated through the carbonyl oxygen atoms. On heating the endothermic removal of two pypr ligands occurs in the first stages of decomposition and at higher temperatures the Co/sac intermediate decomposes to Co3O4 and finally to CoO.
