metal-organic compounds
The title compound, {[Ba2(C13H8N2O6S)2(H2O)6]·C10H8N2}n, possesses a novel two-dimensional porous coordination network, in which each BaII ion is nine-coordinated by three carboxylate O atoms, two sulfonate O atoms and four water molecules in an irregular coordination environment. Hydrogen-bond interactions between coordinated water molecules and sulfonate/hydroxyl groups hold the network layers together and produce a three-dimensional supramolecular architecture.
organic compounds
Two 1:1 proton-transfer complexes of sulfobenzoic acids with aromatic amines, namely 4-[2-(4-pyridyl)ethenyl]pyridinium 2-carboxybenzenesulfonate, C12H11N2+·C7H5O5S-, (I), and 1,10-phenanthrolin-1-ium 4-carboxybenzenesulfonate dihydrate, C12H9N2+·C7H5O5S-·2H2O, (II), have very different hydrogen-bonding patterns compared with reported organic sulfobenzoic acid complexes. In (I), two cations and two anions form a four-molecule loop, in which ![[pi]](/logos/entities/pi_rmgif.gif)
- interactions occur. In (II), the anions and water molecules form a three-dimensional hydrogen-bonding network, while the cations only act as pendant components. The water molecules play a central role in the formation of the abundant hydrogen-bonding architecture in (II). The relative poorness and richness of hydrogen bonds in (I) and (II), respectively, give rise to novel hydrogen-bonding patterns.
