Figure 3
The asymmetric unit of chloro­form solvate (IIa)[link], showing the atom-numbering scheme and the dimerization of the host mol­ecules via hydrogen bonding (dashed lines). Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. The chloro­form guest mol­ecule sits on a site of [\overline{4}] symmetry and is thus extensively disordered. The structures of the CCl4, CH2ClCH2Cl and CHCl2CHCl2 solvates, viz. (IIb)[link], (IIc) and (IId), respectively, are ostensibly the same, but the guest solvents in (IIc) and (IId) were too badly disordered to model.
