X-ray crystallographic and molecular modeling studies of 1-(2,6-difluorobenzoyl)-5-(4-chlorophenyl)biuret
Crystals of 1-(2,6-difluorobenzoyl)-5-(4-chlorophenyl)biuret (BFB), C15H10N3O3F2Cl, were grown by evaporation from an acetonitrile solution. Two polymorphs were obtained. The first polymorph (BFB1) crystallized i...
