5,6-Dimethyl-1,10-phenanthroline

S. S. Rozenel

Abstract: In the title compound, C14H12N2, the N...N distance is 2.719 (1) Å. The N-C-C-N torsion angle [0.9 (1)°] is close to the ideal value of 0° as expected. Bond lengths and angles are consistent with those observed for [1,10]phenanthroline and coordinated 5,6 dimethyl[1,10]phenanthroline. In the crystal, C-H...N hydrogen bonds link the molecules into C(4) chains running parallel to the b axis. Weak [pi]-[pi] interactions between benzene and pyridine rings [centroid-centroid distance = 3.5337 (7) Å] and between benzene rings [centroid-centroid distances = 3.6627 (7) and 3.8391 (7)Å] also occur.
