Abstract

In the 2:1 adduct of 2,2'-biphenol and 1,4-diazabicyclo[2.2.2]octane, 2C(12)H(10)O(2). C6H12N2, there are eight molecules of the biphenol and four molecules of the amine in the asymmetric unit, and several of these components exhibit orientational disorder even at 100 K. Each biphenol unit contains an intramolecular O-H ... O hydrogen bond [O ... O range for the ordered components 2.594(6) to 2.668(5) Angstrom]. Each of the amines is hydrogen bonded to two biphenol units [O ... N range for the ordered components 2.521(7) to 2.594(6) Angstrom], so forming four independent three-molecule aggregates. These aggregates are further linked by an extensive series of C-H ...pi(arene) interactions into a continuous three-dimensional framework.
