The synthesis and X-ray crystal structure of a novel, cage-functionalized bis(alpha-diketone), 4, is described. A molecular cleft is formed by two parallel planar aromatic diketone units bridged by a polycarbocyclic cage. Crystal data: T 100(l) K, monoclinic, C2/c, a = 35,6383(2), b = 11.8110(l), c = 15.6319(2) Angstrom, beta = 110.7745(2)degrees, V = 6152.04(9) Angstrom(3), Z = 12, R = 0.0691. Compound 4 is of potential interest as a new type of "host" molecule for the study of host-guest interactions in solution.
