Abstract
The template reaction of 2,6-diacetylpyridine with 1,8-diaminonaphthal ene in the presence of calcium(II), strontium(II) and barium(II) nitra tes produced the new hexadentate N4O2 open-chain complexes as a result of [2 + 1] Schiff base condensation, irrespective of the molar ratio of starting materials used in the synthesis. They were characterized b y IR, UV-vis, H-1 NMR and analytical data. No [2 + 2] macrocyclic comp lexes were isolated, either in the template synthesis, nor on the trea tment of the [2 + 1] acyclic complexes with diamine.
