Crystal and molecular structure ofcis-dibenzobicyclo[3.3.0]octa-2,7-diene, C16H14

The structure of the title compound, C16H14, was determined by X-rays:M r =206.29, monoclinic, space groupP21/n,a=5.002(1),b=23.972(5),c=9.505(2) A,β=102.56(2)°,V c =1112.4 A3,Z=4,D x =1.23 Mg m−3, MoKα radiation (graphite crystal monochromator,\(\bar \lambda = 0.71069\) A),μ(MoKα)=0.75 cm−1,T=290 K. Final conventionalR-factor=0.028,R w =0.030 for 742 unique reflections and 187 variables. The structure was solved usingMultan.
