Abstract
The macrocyclic tetradentate N,N,N,N, donor dioxouranium nitrate compl ex of formula [UO2L](NO3)2 . 2H20, (where L is ,11,14-tetramethyl-3,4, 12,13,19,20-hexaazatricyclo ]eicosa-1(19),2,4,6,8,10(20),11,13,15,17-d ecaene), has been prepared by the condensation of 2,6-diacetylpyridine with hydrazine in the presence of a metal ion template and characteri zed by IR, UV-vis, H-1 NMR and MS data. The 2,6-diacetylpyridine dioxo uranium nitrate complex isolated as minor product is regarded as a pos sible intermediate in the condensation reaction leading to the formati on of the macrocyclic complex.
