A template directed [2+2] Schiff base condensation of 2,6-diformyl pyridine and 1,3 diaminopropane afforded the 20 membered Ns macrocycle "VT". The X- ray structure of the barium templated VT has been determined <M. G.B. Drew, at the University of Reading). Complexes of first transition series ions, obtained by transmetallation, have been characterized using electronic, infrared and esr spectroscopy. Results indicate that VT provides a cavity suitable for single atom bridged binuclear assemblies.

The Schiff-base strategy was further used to yield macrobicyclic cyclophanes from the [2+3] condensation of tris(amino ethyl) amine ie tren, with a series of aromatic dicarbonyls. X-ray structures and 'Hnmr. studies show that these macrobicycles have very different conformations in their complexed and uncomplexed forms.
