Proton-transfer and non-transfer in compounds of quinoline and quinaldic acid with L-tartaric acid.
The structures of two compounds of L-tartaric acid with quinoline, viz. the proton-transfer compound quinolinium hydrogen (2R,3R)-tartrate monohydrate, C9H8N+.C4H5O6-.H2O, (I), and the anhydrous non-proton-transfer adduct with quinaldic acid, bis(quinolinium-2-carboxylate) (2R,3R)-tartaric acid, 2C10H7NO2.C4H6O6, (II), have been determined at 130 K. Compound (I) has a three-dimensional honeycom...
متن کاملHydrogen-bonded co-crystal structure of benzoic acid and zwitterionic l-proline
The title compound [systematic name: benzoic acid-pyrrolidin-1-ium-2-carboxyl-ate (1/1)], C7H6O2·C5H9NO2, is an example of the application of non-centrosymmetric co-crystallization for the growth of a crystal containing a typically centrosymmetric component in a chiral space group. It co-crystallizes in the space group P212121 and contains benzoic acid and l-proline in equal proportions. The cr...
متن کاملSupramolecular hydrogen-bonded structure of a 1:2 adduct of melamine with boric acid
Boric acid (B) forms a 2:1 hydrogen-bond adduct, M·2B, with melamine (M), wherein, a finite tetrameric ribbon of boric acid forms hydrogen bonds with the nitrogen donor sites of M. Hydrogen-bonded layers of B and M in the bc-plane are connected by boric acid units along the a-axis to give a three dimensional structure. Interestingly, one of the amino groups of M does not participate in hydrogen...
متن کاملCrystal structures of three hydrogen-bonded 1:2 compounds of chloranilic acid with 2-pyridone, 3-hydroxypyridine and 4-hyroxypyridine
The crystal structures of the 1:2 compounds of chloranilic acid (systematic name: 2,5-di-chloro-3,6-dihy-droxy-1,4-benzo-quinone) with 2-pyridone, 3-hy-droxy-pyridine and 4-hyroxypyridine, namely, bis-(2-pyridone) chloranilic acid, 2C5H5NO·C6H2Cl2O4, (I), bis-(3-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (II), and bis-(4-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (III), ...
متن کاملResonance-stabilized partial proton transfer in hydrogen bonds of incommensurate phenazine–chloranilic acid
The co-crystal of phenazine (Phz) and chloranilic acid (H2ca) becomes ferroelectric upon cooling through the loss of inversion symmetry. Further cooling results in the development of an incommensurate ferroelectric phase, followed by a lock-in transition towards a twofold superstructure. Here we present the incommensurately modulated crystal structure of Phz-H2ca at T = 139 K with a symmetry gi...
