1,5-Di(4,5-disubstituted-2-aminophenyl) penta-1,5-diaza-1,3- dienatonickel(II) chlorides are reacted with formaldehyde and barbituric acid in the presence of catalytic amount of perchloric acid to synthesize two members of a new type of aza macrocyclic complex of Ni(II) . The macrocyclic complexes, which are diamagnetic, have been characterised by conductivity, electronic spectra, thermal analysis and NMR (1H and 13C) spectroscopy. The structure of the cation in one of the macrocyclic complexes has been examined by using molecular mechanics.
