ABSTRACT
The crystal structure of the title compound, C(64)H(52)Br(4)O(8)·1.31C(3)H(6)O·0.69CHCl(3), 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) chloro-form within the mol-ecular structure of the title compound represents a new clathrate of the title compound. One half of the resorcin[4]arene cavitand mol-ecule appears in the asymmetric unit; the complete resorcin[4]arene cavitand structure was generated across a mirror plane.
