Amide nitrogen coordination of Co(II) and Ni(II) in ternary 2,2'-bipyridine-containing systems. A solution and solid state study. JOURNAL OF THE CHEMICAL SOCIETY DALTON TRANSACTIONS; p. , ISSN: 0300-9246

Cobalt(II) and Nickel(II) interactions towards N-protected aminoacid were investigated both in solution and solid state and the ternary compexes with 2,2'-bipyridine. The experimental conditions (pH, metal:ligand:amine ratio) for amide nitrogen deprotonation in ternary systems were defined and the stability constant of ternary complexes were evaluated. The crystal structure of Co(II)bis-tosylglycinato 2,2'-bipyridine complex was determined.
