Abstract Cu (l) and Ag (l) complexes of 1, 4, 5, 8-tetra-azaphenanthrene (TAP) and of two of its methylated derivatives (3, 6-dimethyl-and 2, 3, 6, 7-tetramethyl-) have been made and characterized. Their HNMR spectra are discussed. The structure of the complex Ag (TAP) 2 (NO 3), as determined by X-Ray crystallography, is that of a strongly folded and twisted square planar arrangement of the chelating ligands around the silver atom; the four Ag-N ...
