Highlighted illustration

Cover illustration: The considerably distorted tetrahedral coordination environment of the Ag(I) atom in the complex cation of the salt [Ag(C₁₀H₆N₄)₂]PF₆ is defined by two [kappa] ²N,N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands. Weak intermolecular interactions between the cations result in the formation of interstices in which the PF6^- counter-anions are embedded. See Wang [Acta Cryst. (2012). E68, m5].
