Synthesis and Structures of Silver(I) Adducts with 4-Amino-4H-1,2,4-triazole

Abstract

Reactions of silver(I) salts with 4-amino-4H-1,2,4-triazole (4-NH2-tz) in a 1 : 1 molar ratio yield four new silver adducts, namely [Ag(4-NH2-tz)](CF3SO3) (1), [Ag(4-NH2-tz)1.75](ClO4) (2), [Ag(4- NH2-tz)1.75](BF4) (3) and [Ag(4-NH2-tz)1.75](NO3) (4). X-Ray analysis shows that 1 exhibits a 3D cationic [Ag(4-NH2-tz)]+ metal-organic framework of srs topology; 2, 3 and 4 are isostructural and display an infinite chain structure containing an Ag4tz6 cluster.
