  Syntheses, structures, and properties of Co(III) complexes derived from polypyridine ligands containing one carboxamido nitrogen donor

  摘要：

  Four cobalt(III) complexes containing the polypyridine pentadentate ligands N,N-bis(2-pyridylmethyl)amine-N'-ethyl-2-pyridine-2-carboxamide (PaPY3H), N,N-bis(2-pyridylmethyl)amine-N'-[1-(2-pyridylethyl)acetamide (MePcPy3H), and N,N-bis(2-pyridylmethyl)amine-N'-(2-pyridylmethyl)acetamide (PCPy3H), have been synthesized. All three ligands bind the Co(111) center in the same fashion with the exception of loss of conjugation between the carboxamide moiety and the pyridine ring in the latter two. The structures of [(PaPy3)Co(OH)][(PaPy3)Co(H2O)](ClO4)(3) (.) 3H(2)O (1), [(PaPy3)Co(NO2VClO4) (.) 2MeCN (2), [(MePcPy3)Co(MeCN)](ClO4)(2) (.) 0.5-MeCN (3), and [(PCPy3)Co(Cl)](ClO4) (.) 2MeCN (4) have been determined. These ligands with strong-field carboxamido N donor stabilize the +3 oxidation state of the Co center as demonstrated by the facile oxidation of the corresponding Co(H) complexes (prepared in situ) by H2O2, [Fe(Cp)(2)](BF4), or nitric oxide (NO). The Co-N-amido bond distances of 1-4 lie in the narrow range of 1.853-1.898 angstrom. H-1 NMR spectra of these complexes confirm the low-spin d(6) ground states of the metal centers.

  The present nitrosyls, namely [(PcPy(3))Fe(NO)](ClO(4))(2) (2) and [(MePcPy(3))Fe(NO)](ClO(4))(2) (3), belong to the same (Fe-NO)6 family and exhibit (a) clean (1)H NMR spectra in CD(3)CN indicating S = 0 ground state, (b) almost linear Fe-N-O angles (177.3(5) degrees and 177.6(4) degrees for 2 and 3, respectively), and (c) N-O stretching frequencies (nu(NO)) in the range 1900-1925 cm(-)(1).
