“…The title salt constitutes a new example of dialkylammonium hydrogenoxalates and thus supplements the number of crystal structures resolved to date for this type of salt (Birnbaum, 1972;Thomas & Pramatus, 1975;Thomas, 1977;Gü ndisch et al, 2001;Warden et al, 2005). In addition, ISSN 2056-9890 and because of their capacity to easily develop hydrogenbonding networks, carboxylic acids and their derivatives are of great interest in the field of crystal engineering, leading to a large diversity of supramolecular topologies (Ivasenko & Perepichka, 2011).…”
