## Abstract A series of NβNβN terdendate polypyridine type ligands and their NβCβN cyclometalating homologues were synthetized and fully characterized (L~1~βL~12~). Complete assignments of the ^1^H spectra of the various compounds, accomplished by using a combination of oneβ and twoβdimensional nmr
The X-Ray structures of the 1:l copper(I1) complexes with racemic and optically active (+)-(R,R)-(2,6bis(pyrro1idin-2-y1)pyridine ((+)-bpp; (+)-I) were determined. Whereas the perchlorate 1 of the racemic complex contains the monomeric units with perfect C, symmetry, the sulfate of the optically act
