• The crystal structure and phase transition of acetylene were studied by means of a low-temperature X-ray single crystal technique. The crystal showed a lattice transformation at about -140℃. The high-temperature modification was cubic with four molecules in a cell of the dimension a=6.14A at -117℃, the space group being T_h^6-Pa 3. The parameters of carbon and hydrogen atoms were determined by the Fourier method. The molecular dimensions derived from the parameters were C≡C=1.20A and C-H=1.05A, the molecule being linear. The closest approach between neighboring molecules were H…H=3.28A and C…C=3.89 A. preliminary results of the low-temperature structure based on powder photographs are also described.
