Conclusions

  1. 1.

    The x-ray diffraction analysis of the structure of E-benzylidene(diphenylmethylene)-succinic anhydride has been carried out.

     
  2. 2.

    The direction of the photo- and thermochromic cyclization reaction of this compound is controlled by steric factors; the phenyl substituent of the diphenylmethylene fragment appears to be drawn closer to the reactive methylene center corresponding to it in comparison with the phenyl substituent of the benzylidene fragment.
