- 2-Hydroxybenzyl alcohol–phenanthroline (1/1) (2009)
- Crystals of the title compound, C12H8N2·C7H8O2, were obtained during cocrystallization experiments of a compound with two hydrogen-bond donors (2-hydroxybenzyl alcohol) with another compound containing two hydrogen-bond acceptors (phenanthroline). Unexpectedly, the two molecules do not form dimers with two O—H ... N hydrogen bonds connecting the two molecules. However, one of the hydroxy groups forms a bifurcated hydrogen bond to both phenanthroline N atoms, whereas the other hydroxy group forms an O—H ... O hydrogen bond to a symmetry-equivalent 2-hydroxybenzyl alcohol molecule. In addition, the crystal packing is stabilized by Pi – Pi interactions between the two phenanthroline ring systems, with a centroid–centroid distance of 3.570 Å.
- Bis(2,6-dicarboxypyridinium) dichloride acetone monosolvate (2009)
- The title compound, 2C7H6NO4 +·2Cl-·C3H6O, crystallizes with two 2,6-dicarboxypyridinium cations, two chloride anions and one acetone molecule in the asymmetric unit. The crystal structure is characterized by alternating cations and by Cl- anions, forming zigzag chains running along the a axis.
- Pyridinium-2-carboxylate–benzene-1,2-diol (1/1) (2009)
- The title compound, C6H5NO2·C6H6O2, crystallizes with one pyridinium-2-carboxylate zwitterion and one molecule of benzene-1,2-diol in the asymmetric unit. The crystal structure is characterized by alternating molecules forming zigzag chains running along the a axis: the molecules are connected by O—H ... O and N—H ... (O,O) hydrogen bonds.
