Polynuclear complexes of cobalt(II) with 2-dipicolylamine and 2-aminomethylpyridine

Polynuclear complexes of cobalt(II) with 2-dipicolylamine and 2-aminomethylpyridine. Huchital, Daniel H.; Debesis, Eileen (Dep. Chem., Seton Hall Univ., South Orange, NJ 07079, USA). Inorg. Chim. Acta, 126(2), 167-71 (English) 1987. CODEN: ICHAA3. ISSN: 0020-1693. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 67 The hypothesis (H. and D., 1985) that the blue color of basic anaerobic solns. of Co(II) with 2-aminomethylpyridine (AMP) and di-2-picolylamine (DPA) is due solely to deprotonation of the ligand amine was modified. Deprotonation does occur, but only as an intermediate step in the reaction. Co(II) and AMP form stable dimers and polymers in these solns. The dimerization and polymn. are competitive reactions, the former being directly and the latter inversely dependent on the OH- concn. 108638-64-8 and 1539-42-0 which are cas registry numbers of chemicals are mentioned. In the dimer reported earlier, the 2 metal centers are linked by 1 m-hydroxo and 2 m-amido bridges. In the polymer reported here, metal atoms are linked by a m-amido bridge, with m-hydroxo bridges between alternate metal atoms. Blue complexes of Co(II) with DPA contain 1 mol of ligand per mol of Co(II). The dimer is not stable and polymn. readily occurs. The polymer contains 1 m-hydroxo and 1 m-amido bridge between each pair of metal atoms. .

DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75 The trinuclear Co(III) complex with the partial cubane Co3O4 core, [Co3(dpa)3(m-OH)3(m3-O)]Cl4 (dpa: bis-(2-pyridylmethyl)amine), was prepd. and the crystal structure was detd. for the dithionate salt, [Co3(dpa)3(m-OH)3(m3-O)](S2O6)2.7H2O, by the x-ray diffraction method. Though the partial cubane structure was slightly distorted by the N-H U H-N repulsive interaction, this complex is stable at least 5 days in neutral aq. soln. .
