摘要：

The X-ray crystal structure of the complex formed between 1,2-bis(3'-pyridyl)ethyne and C-methylresorcinarene is described. The structure (C45H47N3O12) is monoclinic with a=11.8086(7), b=31.2037(17), c=11.2933(6)Angstrom, beta=101.9330(10)degrees and space group P2(1)/c. The structure reveals that the resorcinarene adopts the common bowl-shaped conformation however the four intramolecular hydrogen bonds are arranged asymmetrically. One of the pyridyl rings sits inside the resorcinarene and is hydrogen bonded to two adjacent resorcinarenes.
