4-[4-(dimethylamino)benzylideneamino]-3,5-bis(2-pyridyl)-4H-1,2,4-triazole.

The title compound, C(21)H(19)N(7), is a polypyridine ligand that is suitable for assembling complex metal systems capable of photoinduced electron transfer. The solid-state structure has been determined at room temperature by single-crystal X-ray diffraction. The molecule is not flat and both the bis(pyridyl)triazole and the benzylideneamine fragments show significant distortions from planarity.
