Abstract: The crystal structure of 5[(4'-heptoxy-biphenylyl-4-yl)oxy]carbonyl-1-pentyne(A3E'O7) was investigated by wide angle X-ray diffraction(WAXD), transmission electron microscope(TEM) and atom force microscope(AFM). The structures of A3E'O7 solution-crystal and melt-crystal are the same. The crystals belong to the monoclinic P112/m space group, the cell parameters are a0.589 nm, b0.771 nm, c4.75 nm, αβ90° and γ93.8°, the calculated cell density is 1.167 g/cm3.

Key words: Crystal structure, 5[(4'-Heptoxy-biphenylyl-4-yl)oxy]carbonyl-1-pentyne(A3E'O7), TEM, X-ray diffraction
