title: Solid-state structural transformations of two Ag(I) supramolecular polymorphs to another polymer upon absorption of HNO3 vapors.
abstract: Solid-state structural transformation of two polymorphic forms of [Ag(8-HqH)(8-Hq)]n (1α and 1β, where 8-HqH = 8-hydroxyquinoline and 8-Hq(-) = 8-hydroxyquinolate) to {[Ag(8-HqH)2]NO3}n (2) has been observed upon solid-gas reaction of compounds 1α and 1β with HNO3 vapors. Solid-gas reaction of compound 2 with hydrated vapors of NH3 results in the formation of only the 1β polymorph, while solid-solid reaction of compound 2 with KOH results in the formation of a 1α and 1β mixture with chiral and achiral space groups of P2(1)2(1)2(1) and Pbcn, respectively.
