Ps. Wheatley et al., Linking of C-4(4)(32)[R-4(4)(30)] chains of rings in the hydrogen-bonded adduct 3,5-dihydroxybenzoic acid-4,4 '-bipyridine (2/3) by means of pi center dot center dot center dot pi stacking interactions, ACT CRYST C, 55, 1999, pp. 1489-1492
In the 2:3 adduct of 3,5-dihydroxybenzoic acid and 4,4'-bipyridine, 2C(7)H(
