Abstract

The stepwise syntheses of one symmetric and three asymmetric tetraazabis(tropocoronand)s (12a-12d) having two linker chains, with or without a hydroxy group, of the same or different length are reported. The coordination styles of their nickel(Ö†) complexes (13a-13d) in solution have also been discussed based on their 1H NMR and UV-VIS. spectral data.
