Ferrocene-1,1′-dicarboxylic acid as a building block in supramolecular chemistry: supramolecular structures in one, two and three dimensions

Ferrocene-1,1′-dicarboxylic acid forms adducts with a wide range of organic amines: the structures of nine examples show that most are salts and that hydrogen bonds of O—H...O, O—H...N and N—H...O types can link the components into one-, two- or three-dimensional arrays.

Structures of three substituted arenesulfonamides from X-ray powder diffraction data using the differential evolution technique

The crystal structures of three substituted arenesulfonamides have been solved from X-ray powder diffraction data using a new direct-space structure solution method based on a differential evolution algorithm: N—H...O hydrogen bonding leads to supramolecular aggregates in three, two or one dimensions, modified in some cases by C—H...O hydrogen bonds and aromatic π...π stacking interactions.

Nine isomeric nitrobenzylidene-iodoanilines: interplay of C—H...O hydrogen bonds, iodo...nitro interactions and aromatic π...π stacking interactions

In crystalline nitrobenzylidene-iodoanilines, isolated molecules may occur, or the molecules may be linked by some combination of C—H...O hydrogen bonds, iodo...nitro interactions and aromatic π...π stacking interactions, so giving overall supramolecular structures in zero, one, two or three dimensions.
