Abstract
A simple, direct route from 2,2′-bipyridine to 6,6′-dicyano-2,2′-bipyridine and its conversion to the 6,6′-dithiocarboxamide and various novel tetra- and hexa-dentate ligands such as the 6,6′-bis(4-methylthiazol-2-yl) and 6,6′-bis[4-(2-pyridyl)thiazol-2-yl] derivatives have been established. Diaqua[6,6′-bis(4-methylthiazol-2-yl)-2,2′-bipyridine]zinc(II) bis(trifluoromethanesulfonate) has been prepared and its crystal structure determined. The tetra-heterocyclic ligand is planar, binding through two bipyridine nitrogen atoms and, more weakly, through two thiazolyl nitrogen atoms to zinc(II) which is in a distorted octahedral environment.
