The potential of CH···N interactions in determining the crystal structures of novel 3,4-disubstituted-5-pyridinyl-isoxazoles

The crystal structures of novel 3,4-disubstituted-5-pyridinyl-isoxazoles, such as 3-methyl-4-phenyl-5-pyridinyl-isoxazole (1), 4-methyl-3-phenyl-5-pyridinyl-isoxazole (2) and 3,4-diphenyl-5-pyridinyl-isoxazole (3), are governed by significant CH···N interactions.
