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

Journal article, 2013

The structure of 2,3,6,7,10,11-hexahydroxytriphenylene (hhtp) methanol monosolvate, C18H12O6•CH3OH, has triclinic symmetry (space group P1). The compound has a threedimensional 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.
