1,4-Diaza-bicyclo-[2.2.2]octa-ne-trans,trans-hexa-2,4-dienedioic acid (1/1).

ABSTRACT: The title 1:1 co-crystal, C(6)H(12)N(2)·C(6)H(6)O(4), the dicarb-oxy-lic acid mol-ecule is close to planar [r.m.s. deviation from the mean plane = 0.07 (1) Å]. In the crystal, the two mol-ecules are arranged alternately and are linked by O-H⋯N hydrogen bonds, leading to the formation of a chain along the [20-1] direction. The chains are assembled into a two-dimensional framework parallel to the (102) plane through weak C-H⋯O hydrogen bonds between the two types of mol-ecules.
