✦ Synopsis

The title inclusion compound, 2C 15 H 10 F 6 O 2 Á3C 6 H 6 , has an organic zeolite-type structure. The diol molecules selfassemble to form a three-dimensional framework through O-HÁ Á ÁO hydrogen bonds and possible FÁ Á ÁF interactions, whereas the benzene molecules are trapped in channel-like cavities of the host framework by weak crystal packing forces. One of the guest molecules, located on a twofold axis, is disordered over two sites with equal occupancies.

The complete molecule of the title compound, C~18~H~18~N~4~, is generated by crystallographic twofold rotation symmetry, with two C atoms lying on the rotation axis. The pair of pyridyl rings form a dihedral angle of 78.4 (2)° and the dihedral angle between the pyridyl ring and the central benzene r
