Abstract

Abstract: A new BIZ (cobalamin, Cbl) model system with the potentially quinquedentate ligand, 2, 3, 9, 10-tetramethyl-6, 2-pyridylmethyl-l, 4, 8, 1 l-tetraazaundeca-1, 3, 8, lO-tetraen- l, ll-diolo (Clpy), has unique properties attributable to the coordinated pendant pyridine, which is attached covalently at the 2-position by a one-methylene link to the central C of the propylene chain of (DO)(DOH) pn (M', N2'-propanediylbis (2, 3-butanedione 2-imine 3- ...
