The title compound, C~7~H~5~ClF~3~NO, was synthesized by the reaction of 2-chloro-3-hydroxypyridine with 2-chloro-1,1,1-trifluoroethane. The pyridine ring and the O and Cl atoms are nearly coplanar, the largest deviation from the mean plane being 0.078β (6)β Γ . Bioassay indicates that the title compou

The title compounds have been prepared. Infrared spectra of these compounds indicate that titanium is four-coordinate in them. These compounds form complexes of the type Ti(OR)C13~L or 2L (where R = CzH4CI or CzHzF3 and L is monodentate ligand) with various oxygen and nitrogen ligands. The complexes
