## Abstract The complexoneβlike tetraazamacrocycle **1** (LH~4~) forms a series of metal complexes with Co^2+^, Ni^2+^, Cu^2+^ and Zn^2+^ (M^2+^) of the type MLH~2~, ML^2β^ and M~2~L, which have been isolated and characterized by VIS., IR. and NMR. spectroscopy. Based on these results tentative str
The constitution of 6 was established by elemental analysis, the mass spectrum," O1 the relatively high-field position of the 31P NMR signal (6 = -87.6), and the appearance of two sets of pseudoquintets for the trimethylsilyl groups in the 'H and I3C NMR spectra.["lThe expected steric crowding of th
