Abstract: High Resolution Image Download MS PowerPoint Slide The crystal structures of all four ambient-condition gaseous butene isomers have been determined, for the first time, by high-pressure single-crystal X-ray diffraction. 1-Butene (but-1-ene, B ), cis-2-butene ((2 Z )-but-2-ene, CB ), trans-2-butene ((2 E )-but-2-ene, TB ), and isobutene (2-methylprop-1-ene, IB ) at high pressure and room temperature froze at 3.65, 1.55, 0.50, and 1.40 GPa, respectively. B, CB, TB, and IB crystallize in the centrosymmetric space groups of Pnma, C 2/ c, P 2 1 / c, and P 6 3 / m, respectively. All of these crystals remain stable within the investigated pressure range. The physical properties of the studied butene isomers have been correlated with their molecular structures, interatomic distances, and molecular packing.
