Hydrophobic and metal coordination interacted architecture based on p-tert-butylthiacalix[4]arene-potassium complex and its vapor absorption capability

Single-crystal X-ray diffraction studies of [K(1.3H)]center dot 2MeOH complex obtained from p-tert-butylthiacalix[4]arene (1.4H) with KH, which shows two dimer formations. One of the dimers is formed by a hydrophobic interaction between each tert-butyl group of 1.3H and the cavity of another 1.3H in the crystalline state. The other dimer made metal coordination S center dot center dot center dot K center dot center dot center dot(O,S,O) between neighboring 1.3H and potassium ion. In the overall structure, this complex indicates non-porous structure and the adsorption capabilities toward gaseous organic molecules. (c) 2008 Elsevier Ltd. All rights reserved.
