G. Ferguson et al., A PERFORATED MOLECULAR TAPE IN THE 1 1 SALT OF 4,4'-TRIMETHYLENEDIPYRIDINE AND 1,3,5-BENZENETRICARBOXYLIC ACID/, Acta crystallographica. Section C, Crystal structure communications, 54, 1998, pp. 418-421
The 1:1 adduct formed between 4,4'-trimethylenedipyridine and 1,3,5-be
nzenetricarboxylic acid is a salt, C13H15N2+.C9H5O6-. The components a
re linked by a combination of O-H ... O, O-H ... N, N-H ... O and C-H
... O hydrogen bonds into molecular tapes perforated by R-4(4)(38) rin
gs: these tapes are connected by further C-H ... O hydrogen bonds into
a three-dimensional network.
