A systematic study of the crystallisation products of a series of dicarboxylic acids with imidazole derivatives
A systematic study of the crystallisation products of a series of dicarboxylic acids with imidazole derivatives
Nineteen new crystal structures are reported containing alpha,omega-alkanedicarboxylic acids (HOOC-(CH(2))(n-2)-COOH, n = 0-6), maleic acid and fumaric acid with imidazole, 1-methylimidazole, 2-methylimidazole, 4-methylimidazole and 1,2-dimethylimidazole. These were characterised by single crystal X-ray diffraction at 120 K and their crystal structures are discussed together with five published structures. In all of the characterised acid-base combinations at least one of the acidic hydrogens has been transferred to the base and most have a 1 : 1 stoichiometry. Nearly two thirds of the crystal structures adopt a basic sheet topology containing hydrogen bonded anion chains linked by cations. The sheet topologies have been classified based upon the principles of a scheme proposed by MacDonald et al. (J. C. MacDonald, P. C. Dorrestein and M. M. Pilley, Cryst. Growth Des., 2001, 1, 29-38).

Abstract
Nineteen new crystal structures are reported containing alpha,omega-alkanedicarboxylic acids (HOOC-(CH(2))(n-2)-COOH, n = 0-6), maleic acid and fumaric acid with imidazole, 1-methylimidazole, 2-methylimidazole, 4-methylimidazole and 1,2-dimethylimidazole. These were characterised by single crystal X-ray diffraction at 120 K and their crystal structures are discussed together with five published structures. In all of the characterised acid-base combinations at least one of the acidic hydrogens has been transferred to the base and most have a 1 : 1 stoichiometry. Nearly two thirds of the crystal structures adopt a basic sheet topology containing hydrogen bonded anion chains linked by cations. The sheet topologies have been classified based upon the principles of a scheme proposed by MacDonald et al. (J. C. MacDonald, P. C. Dorrestein and M. M. Pilley, Cryst. Growth Des., 2001, 1, 29-38).
