资源简介:
3-Fluorobenzoylaminophenyl 3-fluorobenzoate crystallizes in dimorphic forms, generated by a delicate balance of strong and weak intermolecular forces, one form containing a trapped cyclohexane molecule in the crystalline lattice. Both forms crystallize as triclinic systems with centrosymmetric space group P1̄. The supramolecular features in both forms is guided by control of strong N−H···O hydrogen bonds, weak but directional C−H···O and C−H···F interactions involving disordered fluorine, and isotropic C−H···π and aromatic π···π stacking interactions that differentiate the packing in the two forms. The extent of disorder associated with organic fluorine is different in both forms.
