Abstract
4,4'-Bipyridine (BPY) and 2,3,5,6-tetrahydroxy-1,4-benzoquinone (THBQ) crystallize in a 3:2 ratio as a neutral molecular adduct, 3C(10)H(8)N(2).2C(6)H(4)O(6), in space group P1. There are two independent and centrosymmetric THBQ molecules and two different BPY molecules in the asymmetric unit, one of which lies about an inversion centre. The molecules link together through O-H...O and O-H...N hydrogen bonds to form three interpenetrating networks which create a 'superlattice' of three times the volume of the primitive cell.
