Abstract

The template reaction of 2,6-diacetylpyridine with 1,8-diaminonaphthalene in the presence of calcium(II), strontium(II) and barium(II) nitrates 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 by IR, UV-vis, 1H NMR and analytical data. No [2 + 2] macrocyclic complexes were isolated, either in the template synthesis, nor on the treatment of the [2 + 1] acyclic complexes with diamine.

      Coumarilic acid, a derivative of coumarin (benzo[b]furan-2-carboxylic acid, HCCA, Fig. 1), is a ligand that shows monoanionic monodentate or monoanionic bidentate bonding properties through its carboxylic acid group. The benzo[b]furan ring, which forms the main body of the structure, exists as a key pharmacophore in most of the compounds and can be isolated from natural sources 1–25,26a,b,27–51. Benzo[b]furan and its derivatives are known to be found in different natural food sources such as fruits, herbs and vegetables [2].

      The crystal structures of the Ni(II) [19,20], Mg(II) [21], Co(II) [22], Zn(II) [23] orotate complexes have been described where orotate dianions act as bidentate ligand. The complexes of alkaline earth metal cations have recently received an increasing attention in bioorganic chemistry [24]. The coordination behavior of Mg2+ and Ca2+ has attracted the interest of many researches because of the significant role of these ions in biological processes [25–27].
