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)]·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⋯K⋯(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.
