Reactions of silver salts with 4-amino-3,5-diisopropyl-1,2,4triazole (L) afford dinuclear complex [Ag(2)L(2)(NO(3))(2)(CH(3)CN)], triangular complex [Ag(3)L(3)](CF(3)SO(3))(3), and cyclic tetranuclear complexes [Ag(4)L(6)](BF(4))(4) and [Ag(4)L(6)J(CIO(4))(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. (1)H NMR and MS measurements suggest that these complexes probably retain their structural integrities in CH(3)CN solution.
