6,7-Dihydro-3H-1,4-diazepino[1,2,3,4-lmn][1,10]phenanthroline-3,9(5H)-dione.

ABSTRACT: In the title compound, C(15)H(12)N(2)O(2), the seven-membered ring bearing the three methyl-ene C atoms displays a puckered conformation, with the methyl-ene C atoms deviating from the plane of the benzene ring by 0.05?(1), 0.98?(1) and 1.04?(1)?Å. The phenanthroline unit is not planar; the dihedral angles between this benzene ring and the other pyridyl rings are 9.62?(4) and 9.31?(4)°. The crystal packing is stabilized by ?-? inter-actions between two phenanthroline ring systems, forming a centrosymmetric dimer with a centroid-centroid distance of 3.656?(1)?Å.

In the title compound, C(15)H(12)N(2)O(2), the seven-membered ring bearing the three methyl-ene C atoms displays a puckered conformation, with the methyl-ene C atoms deviating from the plane of the benzene ring by 0.05 (1), 0.98 (1) and 1.04 (1) Å. The phenanthroline unit is not planar; the dihedral angles between this benzene ring and the other pyridyl rings are 9.62 (4) and 9.31 (4)°. The crystal packing is stabilized by π-π inter-actions between two phenanthroline ring systems, forming a cent  ...[more]
