Anion induced structural transformation in silver-(3,6-dimethoxy-1,2,4,5-tetrazine) coordination polymers under mechanochemical conditions

Abstract

Mechanochemical reactions of 3,6-dimethoxy-s-tetrazine (dmotz) with AgCF₃SO₃ and AgClO₄ afforded the 1D linear polymer [Ag(dmotz)(CF₃SO₃)]_n (1) and the 2D grid polymer {[Ag(dmotz)₂](ClO₄)}_n (2), respectively. Mechanochemical processes convert 1 to 2 in the presence of an equivalent of [ClO₄]⁻ and dmotz; even on using excess [CF₃SO₃]⁻, conversion from 2 to 1 was not observed.
