A new methanol solvate and Hirshfeld analysis of π-stacking in 2,3,6,7,10,11-hexahydroxytriphenylene solvates

Abstract

The structure of 2,3,6,7,10,11-hexahydroxytriphenylene (hhtp) methanol monosolvate, C18H12O6·CH3OH, has triclinic symmetry (space groupP\overline{1}). The compound has a three-dimensional layered network structure formed by intermolecular hydrogen bonding. Structure analysis with Hirshfeld surfaces is shown to be a sensitive method for comparing π-stacking effects in the five known solvates of hhtp. The title structure shows slightly weaker π-stacking than the dihydrate, but stronger π-stacking than the other three solvates.
