Abstract Two silver (I) complexes {[1-R-4-(Nt-butylacetamido)-1, 2, 4-triazol-5-ylidene] 2 Ag}+ Cl−[R= Et (1b), i-Pr (2b)] of N/O-functionalized N-heterocyclic carbenes derived from 1, 2, 4-triazoles are reported. The silver complexes, 1b and 2b, have been synthesized from the reaction of the N/O-functionalized triazolium chloride salts namely, 1-R-4-(Nt- butylacetamido)-1, 2, 4-triazolium chloride [R= Et (1a), i-Pr (2a)] by treatment with Ag 2 O ...
