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

A. Karmakar, A. E. Platero-Prats and L. Öhrström

Abstract: The structure of 2,3,6,7,10,11-hexa­hydroxy­triphenyl­ene (hhtp) methanol monosolvate, C18H12O6·CH3OH, has triclinic symmetry (space group P\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 [pi]-stacking effects in the five known solvates of hhtp. The title structure shows slightly weaker [pi]-stacking than the dihydrate, but stronger [pi]-stacking than the other three solvates.

Formula: C18H12O6·CH4O
