2,9-Bis(4-pyridylmethoxy)-1,10-phenanthroline

In the title molecule, C24H18N4O2, the dihedral angles between the mean plane of the phenanthroline ring system and the pyridine rings are 82.52 (5) and 71.58 (4)°. The dihedral angle between the two pyridine ring planes is 53.54 (6)°. In the crystal structure, there are π–π stacking interactions between 1,10-phenanthroline rings, with centroid–centroid distances of 3.6101 (11) and 3.5864 (11) Å
