N-(9,9-Dipropyl-9H-fluoren-2-yl)-7-(piperidin-1-yl)-2,1,3-benzothia­diazol-4-amine

In the title compound, C₃₀H₃₄N₄S, each of the benzothia­diazole and fluorene fused ring systems is almost planar (r.m.s. deviations = 0.010 and 0.013 Å, respectively) and they are inclined to each other with a dihedral angle of 61.69 (3)°; the S atom is directed away from the rest of the mol­ecule. Each of the benzothiadiazole ring N atoms forms a significant intra­molecular contact, i.e. N—H...N or C—H...N. In the crystal, linear supra­molecular chains along the c axis are generated by C—H...N inter­actions involving the tertiary amine N atom.
