Abstract

In the title compound, C17H15ClF3N5O4, the piperazine ring has a chair conformation, with the benzene and pyridine rings attached to the piperazine in equatorial positions. In addition, C—H...N, C—H...O and C—H...F intermolecular hydrogen bonds link molecules into a two-dimensional network structure. The F atoms are disordered over two sites in an approximately 5:1 ratio. [ABSTRACT FROM AUTHOR]
