    Abstract

    The podand, bis(2-methoxyphenoxy)w-xylene (1), was designed and synthesized as a potential host for the cesium ion. Its structure was determined by single crystal X-ray diffraction. It crystallizes in P2 1/c with cell dimensions: a = 8.5723(7) Å, b = 8.3931(14) Å, c = 25.2879(26) Å, β = 96.224(9)°, and V = 1808.7(4) Å 3. A crown derivative, tribenzo-21-crown-6 (2), was also prepared and structurally characterized. It also crystallizes in P2 1/c with cell dimensions: a = 15.5825(13) Å, b = 15.8648(16) Å, c = 8.8266(7) Å, β = 95.247(6)°, and V = 2172.9(3) Å 3. The structures exhibit hydrogen bonding, and are evaluated in terms of complementarity and preorganization for cesium binding.
