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

摘要

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 pyrazole rings is 87.65 (3)°. In the crystal structure, weak inter­molecular C—H⋯N inter­actions link the mol­ecules into chains. The π–π contacts between the naphthyridine rings and the naphthyridine and thio­phene rings [centroid–centroid distances = 3.766 (3) and 3.878 (3) Å] may further stabilize the structure. A weak C—H⋯π inter­action is also present.
