Abstract: In the title molecule, C24H16N4O·H2O, the benzene ring of the 1,10-phenanthroline group and that of the 2-phenylpyridine 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 molecule is hydrogen bonded to one of the phenanthroline N atoms. In the crystal structure, significant - stacking interactions occur, with centroid-to-centroid separations in the range 3.567-3.681 (2) Å.
