3,6-Dimethyl-1-phenyl-4-(2-thienyl)-8-(2-thienylmethylene)-5,6,7,8-tetrahydro-1H-pyrazolo[3,4-b][1,6]naphthyridine

In the molecule of the title compound, C26H22N4S2, the pyrazole ring is oriented at a dihedral angle of 0.85 (3)° with respect to the adjacent naphthyridine ring, while the other ring of naphthyridine adopts an envelope conformation. The dihedral angle between phenyl and p...
