structure and hydrogen bonding

Chioranil and bromanil are isomorphous. The cell constants are a0 =8.624 , b0 =6.173 , c0 =9.027Å, β=74.2° for bromanil. There are two molecules in the unit cell, and the space group is P 21/ a ( C 25h ). The crystal consists of two layers of substituted halogen atoms which are parallel to the (001) plane, and the skeletons consisting of oxygen and carbon atoms lie between these two layers[1].
