Notes: 2,2′-Bipyridine (2BPY) and hexahydroxybenzene (HHB) crystallize in a 2:1 ratio as a neutral molecular adduct, C6H6O6·2C10H8N2, in space group P\overline 1 with Z = 1 and with the HHB molecule lying on an inversion centre. HHB, of which this is the first single-crystal X-ray structure determination, forms O—H...O hydrogen-bonded chains parallel to the a axis, with O...O distances of 2.761 (1) and 2.782 (1) Å. O—H...N hydrogen bonds to the 2BPY molecules crosslink these chains, with O...N distances of 2.707 (1) and 2.735 (1) Å.
