A 1,2-Dihydrodipyrido-pyrazol-2-one

The pyrazole and pyridine rings in the pyrazolo(1,5-a>-pyridine skeleton of 1-ethyl-2-oxo-1,2-dihydrodipyridopyrazole-3-carbonitrile, C13H10N4O, are planar , and are almost coplanar to each other with a dihedral angle of 0.9 (3) deg.The planar 2-pyridone ring (fused to the pyrazolopyridine ring at the 2- and 3-positions) is also nearly coplanar with the pyrazolopyridine ring .The delocalized ring system extends to the fused 2-pyridone ring.
