Abstract

Imidazolyl and 3'-pyridyl are linked by azo bond (-N=N-) to synthesize hitherto unknown mixed heterocyclic azo molecules, 2-[(3'-pyridyl)azo]imidazole (3'-PyaiH). Alkylation in presence of NaH has synthesized 1-alkyl-2-[(3-pyridyl)azo]imidazole (3'-PyaiR'). 3'-PyaiR' include three types of N-donor centers: N(imidazole), N(azo) and a peripheral N(pyridine). They bind to Ag+ to form 2:2 metallo-macrocycle, [Ag(3'-PyaiR')](2)(2+), while the reaction with Cd2+ forms Cd(3'-PyaiR')(4)(2+). The complexes are structurally characterized by X-ray diffraction studies. (C) 2004 Elsevier B.V. All rights reserved.
