Figure 1
The asymmetric unit of the acetone solvate, (Ia), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level. The acetone guest molecule, which was modelled with isotropic displacement parameters, sits on a site of symmetry and is extensively disordered. The structures of the propan-2-ol, methanol, water and benzonitrile solvates, (Ib)–(Ie), are essentially the same, but the guest solvent molecule in each of (Ic)–(Ie) was too badly disordered to model. |
