Solid-state structural transformations of two Ag(I) supramolecular polymorphs to another polymer upon absorption of
1Department of Chemistry, Faculty of Sciences, Tarbiat Modares University, P.O. Box 14115-175, Tehran, Islamic Republic of Iran.
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.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
Thermal Sigmatropic Reactions: Overview
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred to as...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
