Journal Name ARTICLEThis journal is © The Royal Society of Chemistry 20xx J. Name., 2013, 00, 1-3 | 1 The crystalline binary adduct between the trimethylamine N-oxide (TMANO) and 2,4-dichlorobenzoic acid (2,4-DCBA) molecules was obtained by slow evaporation from acetonitrile. The obtained molecular complex is formed by a racemic mixture of molecular complexes crystallizing in the orthorhombic space group Pbca. An exhaustive analysis of the temperature dependence of the cell parameters and the behavior of the acidic hydrogen position and carboxilate group were studied by single crystal and powder X-ray diffraction, FT-IR spectroscopy and theoretical calculations. The molecular system was thermally characterized, subsequently demonstrating a order-disorder transition. Finally, the intermolecular interactions were analyzed via Hirshfeld surface analysis.

“…Both molecules in the asymmetric unit present differences in the torsion angle around the thiazole ring with values of 24.70(4) and 15.27 6 details about the interactions involved in the formation of the crystal packing. [18][19][20] In the dnorm represented in Figure 5, it is possible to observe contacts shorter than the sum of the van der Waals radii in red, contacts close to their van der Waals limits in white, and the longest contacts in blue. For the dimeric units, present in the asymmetric unit, the red and white colors are positioned around the oxygen, chloride and sulfur atoms that act as acceptor atoms, and over the carbons that act as donor atoms.…”
