Co-ordination-assisted inclusion of neutral molecules by the racemic 9,9′-spirobifluorene-2,2′-dicarboxylic acid host lattice. X-Ray crystal structure of the dimethylformamide clathrate at 170 K
Abstract
The title compound acts as a clathrate host for dimethylformamide (DMF), ethanol, and propan-2-ol; DMF is held inside a rectangular void of the host lattice via hydrogen bonding and steric interaction.
