title: N-(1,10-Phenanthrolin-5-yl)-4-(2-pyridyl)-benzamide monohydrate.
abstract: In the title mol-ecule, C(24)H(16)N(4)O·H(2)O, the benzene ring of the 1,10-phenanthroline group and that of the 2-phenyl-pyridine group are respectively twisted by 67.9 (1) and 15.3 (3)° from the carbamoyl group defined by the plane of the O=C-N group of atoms. The water mol-ecule is hydrogen bonded to one of the phenanthroline N atoms. In the crystal structure, significant π-π stacking inter-actions occur, with centroid-to-centroid separations in the range 3.567-3.681 (2) Å.
