Abstract

Diphenyl(tetrafluoroborato)-λ3-iodane forms 1:1 complexes with pyridine-derived ligands in CD2Cl2 solution and the binding constants decrease in the order: 1,10-phenanthroline > 2,2’:6’,2”-terpyridine > 2,2’-bipyridyl Å` pyridine. The 1:1 complex of the λ3-iodane with pyridine adopts a distorted square-planar geometry around the iodine atom.
