Abstract
The crystal and molecular structure of 1,1-di-(p-nitrophenyl)ethylene has been determined as part of a study on diarylhalogenoethylenes and related compounds. Crystals are monoclinic, space group P21/c, with Z= 4, in a unit cell of dimensions a= 7·978(1), b= 19·386(1), c= 8·304(1)A, and β= 97·12(1)°. The crystal structure was solved by direct methods and has been refined to R= 0·079 for 1590 reflections. Conformational analysis was also carried out by semi-theoretical methods and gave good agreement with the experimental results.
