N,N′-Bis(9-(4-chlorophenyl)-9-xanthenyl)ethylenediamine retains its favoured guest species, 2-methylpyridine, in crystals of the complex by means of a classical (host)N–H⋯N(guest) hydrogen bond.
The favoured guest solvents of (4R,5R)-bis(diphenylhydroxymethyl)-2-spiro-1′-cyclohexane-1,3-dioxolane, pyridine and 3-methylpyridine, were the only guest solvents to experience (host)π⋯π(guest) interactions with this host compound.
The intermolecular (host)π⋯π(host) and (guest)π⋯π(guest) (green dashed lines) and the (guest)C–H⋯π(host) and (host)C–H⋯π(host) (magenta) intermolecular interactions in H1·2(2MP) (in Å), the complex with the preferred pyridyl guest species.
The position of the methyl group in methylpyridine derivatives plays an important role in the copper(II) coordination mechanism and their electrochemical properties relate to the regeneration process of [Cu(dmp)2]2+ at the counter electrode/electrolyte interfaces.
A SeedGel can be formed not only in partially miscible binary solvents but also in miscible binary solvents.
