This molecule is of particular interest in the field of metal\u2013organic frameworks (MOFs), where its hydrolyzed analogue forms MOF structures with high surface areas. The benzene ring which occupies the centre of the molecule forms \u03c0\u2013\u03c0 interactions to the equivalent benzene ring at a perpendicular distance of 3.32\u2005(1)\u2005\u00c5.
