Abstract
Summary 2-Benzylidene[3]ferrocenophane-1,3-dione, C 20 H 14 FeO 2 , crystallizes in the tri-clinic space group P 1 ¯ . The unit cell contains two molecules and has the dimensions: a 8.711(2), b 7.625(2), c 11.908(3)A, α 104.95(5), β 103.86(5), γ 90.17(5)°. The structure was solved using Patterson and Fourier syntheses and refined by the full-matrix least-squares method to a final R value of 0.036 for 2190 reflections. The two cyclopentadienyl rings are tilted 13.57° with respect to each other and staggered by34.10°. The α-carbon atoms are deviated outside the planes of the cyclopentadienyl rings by 0.407 and 0.256A, respectively, both closer to the iron atom. The dihedral angles between the cyclopentadienyl rings and corresponding carbonyl groups are 27.49 and 41.94°.
