Abstract
Mr=248, monoclinic, P21/n, a=12.028 (2), b=7.168( 2), c=15.187 (5) Å , β=91.88(2)°, Z=4, V=1308.6 Å3, Dm=1.26, Dx= 1.263 Mg m-3, λ (Cu Kα)=1.5418 Å, μ=0.86 mm-1, F(000)=536, T=293 K. Final R = 5.6% for 2120 observed reflexions. Owing to the push-pull effect, the C=C bond distance is as long as 1.464 (2) Å with the twist angle about the bond 62.6°.
