Abstract: The crystal structure of the title compound, C64H52Br4O8·1.31C3H6O·0.69CHCl3, is described. The structure has been reported previously [Bryant, Blanda, Vincenti & Cram (1991). J. Am. Chem. Soc. 113, 2167-2172]; however, the lower data acquisition temperature results in an improved refinement model. In addition, the presence of residual acetone and (disordered) chloroform within the molecular structure of the title compound represents a new clathrate of the title compound. One half of the resorcinarene cavitand molecule appears in the asymmetric unit; the complete resorcinarene cavitand structure was generated across a mirror plane.
