Supramolecular Structures in Solid State AgCN–Cd(CN)2–(4-Picoline) Complexes. An Interwoven Double Network of [Cd{Ag(CN)2}2]<i>n</i> in [<i>trans</i>-Cd(4-Mepy)2{Ag(CN)2}2]·(4-Mepy) and a Linear Chain of [–Cd–NC–Ag(CN)Ag–CN–]<i>n</i> in [Cd(4-Mepy)4{Ag2(CN)3}][Ag(CN)2]

Abstract

Abstract The title complexes in the compositions 2Ag(CN)·Cd(CN)2·3(4-Mepy) and 3Ag(CN)·Cd(CN)2·4(4-Mepy) crystallize from the same mother solution with the supramolecular structures remarkably different from each other. The former is a clathrate accommodating a guest 4-Mepy in the interwoven double network host. The latter host is comprised of –Cd(4-Mepy)4–NC–Ag(CN)Ag–CN– linear chains among which discrete [Ag(CN)2]− anions are incorporated.
