ABSTRACT: In the mol-ecule of the title compound, C(26)H(22)N(4)S(2), 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 pyrazole rings is 87.65?(3)°. In the crystal structure, weak inter-molecular C-H?N inter-actions link the mol-ecules into chains. The ?-? contacts between the naphthyridine rings and the naphthyridine and thio-phene rings [centroid-centroid distances = 3.766?(3) and 3.878?(3)?Å] may further stabilize the structure. A weak C-H?? inter-action is also present.
