The co-crystallization of tetra-iso-butyl-resorcin[4]arene I and 2,6-diacetyl-pyridine (Ac(2)py) from MeCN/CH2Cl2 yielded a multi-component complex 1-Ac(2)py-2H(2)O.0.5Me-CN 2, in which the upper rim of 1 is extended supramolecularly by way of hydrogen bonds. Complex 2 (C52H66.5N1.5O14) crystallizes in monoclinic, space group P2(1)/m with a = 10.845(9), b = 20.805(17), c = 12.881 (11) Angstrom, beta = 103.884(19)degrees, V = 2821(4) Angstrom(3), D-c = 1. 102 g/cm(3) and Z = 2. The molecular structure shows that the two adjacent double-stranded arrays as well as linear and zigzag chains generated from Ac(2)py and water bridging to two resorcin[4] arene molecules, respectively, facilitate self-inclusion of one-dimensional hydrogen-bonded polymer.
