The crystal structures and packing of organic compounds in the solid state are determined by the types of bonds between the molecules, the structure will depend upon the number, strength and orientation of inter-molecular interactions and bonds. Piyush Panini and Deepak Chopra of IISER Bhopal looked to investigate this further by synthesising, characterising and crystallising a series of 10 isomeric mono and di-trifluoromethylated benzanilides.
While the traditional C–H – – – O/N type hydrogen bonds are well studied it is more difficult to evaluate some of the weaker interactions, such as those involving halogens. In this Hot Article the authors look to link the cooperative effects of some of the weaker interactions to crystal structures and packing motifs, making some interesting discoveries.
