Abstract

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.
