Abstract
Mr=213.13, orthombic, P212121, a=9.858 (2), b=10.951 (2), c=10.984 (2) Å, V=1185.8 Å3, Z=4, Dm=1.191 (2) (by flotation method in KI solution), Dx=1.194 (2)g cm-3, λ(Mo Kα)=0.7107 Å, μ=0.41cm-1, F(000)=456, T=293K. Final R=0.041 for 875 significant reflections. The C=C bond length is 1.382 (4) Å, significantly longer than that in ethylene, 1.336 (2) Å. The molecular is twisted about the C=C bond by 23.1 (4)° and athe phenyl group is rotated out of the plane of this bond by 39.4 (4)°. Molecular packing is determined by van der Waals forces.
