摘要：

A symmetric hydrogen-bonded liquid crystalline complex was synthesized from 4-n-butyloxy benzoic acid and 1,2-di-(4-pyridyl)-ethylene. The complex was analyzed by optical polarizing microscopy, differential scanning calorimetery, and thermal gravimetric analysis. The existence of hydrogen-bonding for the complex was confirmed by Fourier transform infrared spectroscopy and x-ray crystallography. The liquid crystalline complex crystallizes with a triclinic space group P1with the parameters a = 7.3331(4) angstrom, b = 9.0701(4) angstrom, c = 11.6957(5) angstrom and alpha = 81.896(4)degrees, beta = 79.239(4)degrees, and gamma = 85.652(4)degrees.
