Abstract
New polytopic cryptands 2-4 containing 1,2,4-triazole subunits have be en synthesized by [2+3] condensation of the corresponding acyltriazole 5 and tris(2-aminoethyl)amine (Tren) in excellent yield; 2 and 3 gave dinuclear Ag(I) and trinuclear Cu(I) cryptates, and 4 yielded trinucl ear NI(II) and Cu(II) complexes in alkaline media. The nature of the c omplexes has been established by LSIMS and MALDI-TOF mass spectrometry . (C) 1998 Elsevier Science Ltd. All rights reserved.
