Crystal and molecular structures of sixteen charge-assisted hydrogen bond-mediated diisopropylammonium salts from different carboxylic acids

Diisopropylammonium benzenesulfonate

In the anion of the title molecular salt, C6H16N+·C6H5O3S−, the O atoms of the sulfonate group is rotationally disordered over two sets of sites in a a 0.711 (9):0.289 (9) ratio. The extended structure displays N—H...O hydrogen bonds between the cation and anion, which results in infinite chains propagating parallel to [010]. The chains are linked by weak C—H...O interactions, yielding a two-dimensional network.

Diisopropylammonium hydrogen phthalate

In the crystal of the title molecular salt, C6H16N+·C8H5O4 −, the cation and anions are linked into [010] chains by N—H...O hydrogen bonds. The chains are connected to their neighbours through weak C—H...O hydrogen bonds, leading to a layered supramolecular architecture. The hydrogen phthalate anion exhibits an intramolecular O—H...O hydrogen bond in which the H atom is approximately equidistant to the two O atoms.
