Pr. Meehan et al., MOLECULAR TILING IN THE 1 1-ADDUCT OF 1,4-DIAZABICYCLO[2.2.2]OCTANE AND 1,3,5-BENZENETRICARBOXYLIC ACID/, Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 628-631
The 1:1 adduct formed between 1,4-diazabicyclo[2.2.2]octane and 1,3,5-
benzenetricarboxylic acid is a salt, C6H13N2+.C9H5O6-. The components
both lie on a mirror plane and are linked by O-H ... O, O-H ... N and
N-H ... O hydrogen bonds into planar two-dimensional sheets; these she
ets are formed by repetition of a single R-6(6)(38) ring which thus ge
nerates a tiling pattern with plane group pg.
