title: 1-[2-(Benzyl-amino)-4-pyrid-yl]-2-(4-fluoro-phen-yl)ethane-1,2-dione.
abstract: The crystal structure of the title compound, C(20)H(15)FN(2)O(2), contains two crystallographically independent mol-ecules, which are related by a pseudo-inversion center and linked into dimers via inter-molecular N-H⋯N hydrogen bonds. The 4-fluoro-phenyl ring of mol-ecule A makes dihedral angles of 17.17 (16) and 62.25 (15)°, respectively, with the phenyl and pyridine rings. The 4-fluoro-phenyl ring of mol-ecule B makes dihedral angles of 8.50 (16) and 64.59 (15)°, respectively, with the phenyl and pyridine rings. The dihedral angle between the pyridine ring and the phenyl ring of mol-ecule A [60.97 (15)°] is bigger than in mol-ecule B [59.49 (15)°]. The dihedral angle between the two pyridine rings is 1.37 (14)° and between the two phenyl rings is 3.64 (16)°.
