New pyridine silver(III) complexes have been synthesized by the concurrent
oxidation of silver(I) ion and ammonia in the reaction of pyridine and silv
er nitrate using ammonium peroxydisulfate in aqueous ammonia solution. At h
igh pH values, trans-[Ag(py)(2)(N-2)(2)](OH)(3) was obtained, which was the
n converted to trans-[Ag(py)(2)(N-2)(2)](ClO4)(3). However, at lower pH val
ues [Ag(py)(4)](ClO4)(2)(NO3) was isolated.
