X-Ray Diffraction Structural Studies of a Series of 4-Aryl-1-di-and 4-Aryl-1-trichloromethylisoquinolines and Their 1,2,4-TriazinePrecursors

Structure of two 4-aryl-1-trichloromethylisoquinolines as well as 3-dichloromethyl-6-phenyl-1,2,4-triazine (a synthetic precursor of the corresponding isoquinoline) has been studied by single-crystal X-ray diffraction analysis. The effect of the nature of substituents in the heterocycles on their crystal structure has been shown. The effect of acceptor di- and trichloromethyl groups on the nature of intermolecular interactions realized in crystals has been demonstrated.
