Abstract

The title compound, C(68)H(64)O(8)·C(4)H(8)O(2), is a new resorcin-[4]arene cavitand synthetic precursor, obtained by alkyl-ation of a previously reported resorcin[4]arene. The additional alkyl bridges significantly rigidify the structure and enforce a 'bowl' shape on the mol-ecular cavity. In the crystal structure, the mol-ecule lies on a crystallographic mirror plane, and a single ethyl acetate mol-ecule (also lying on the mirror plane) is present within the compound cavity, illustrating the host capabilities of the mol-ecule.
