Abstract

2,2′-Bipyridine N-oxide(N-bipyO) yields 1:1 complexes with SnCl 4 and SnBr 4 and a 3:1 complex with SnI 4 , by interaction between ligand and salt solutions in carbon tetrachloride. Characterization studies of these complexes led to their formulation as cis -[Sn(N-bipyO)X 4 ] (X=Cl or Br) and [Sn(N-bipyO) 3 ]I 4 . N-bipyO functions as a bidentate O,N-chelating agent in these complexes, coordinating through the N‒O oxygen and through the nitrogen of the pyridine fragment.
