| Summary: | In the title molecule, C25H15BrN2S, the phenanthrene system is slightly skewed, with a dihedral angle of 8.94 (16)° between the outer benzene rings. The imidazole ring makes dihedral angles of 15.18 (16), 2.94 (15) and 88.46 (16)°, respectively, with the thiophene ring, the central benzene ring of the phenanthrene unit and the phenyl ring attached to the latter unit. In the molecule, there are two C—H...π interactions present involving the phenyl ring. In the crystal, molecules are linked by C—H...N and C—H...Br hydrogen bonds, forming zigzag chains along the a axis. The chains are linked by C—H...π interactions, forming a three-dimensional supramolecular structure.
