Abstract

The synthesis and X-ray crystal structure of a novel, cage-functionalized bis(α-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(1) K, monoclinic, C2/c, a = 35.6383(2), b = 11.8110(1), c = 15.6319(2) Å, β = 110.7745(2)°, V = 6152.04(9) Å3, 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.
