摘要
Reactions of silver salts with 4-amino-3,5-diisopropyl-1,2,4triazole (L) afford dinuclear complex [Ag2L2(NO3)(2)(CH3CN)], triangular complex [Ag3L3](CF3SO3)(3), and cyclic tetranuclear complexes [Ag4L6](BF4)(4) and [Ag(4)L(6)J(CIO4)(4)- On the basis of the X-ray analyses, anions are found to play an important role in determining the structures. Through coordination/ noncoordination, anions can impart their influence on the co-ordination geometry of Ag atoms and the angles of N-Ag-N, which seems to be the main factor controlling the nuclearity of the reaction products in this system. H-1 NMR and MS measurements suggest that these complexes probably retain their structural integrities in CH3CN solution. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007).
