The title compound, C 18 H 16 Cl 2 N 2 O 2 , crystallizes with two half-molecules in the asymmetric unit; each molecule lies on an inversion centre. The piperazine ring adopts a chair conformation and the two chlorobenzene rings in each molecule are parallel to each other due to symmetry. The crysta
The title compound, C 26 H 18 Cl 2 O 4 , has two 4-chlorobenzoyl groups that are in an anti orientation and are approximately parallel. The interplanar angle between the mean planes of the two benzene rings is 7.99 (8) . These 4-chlorobenzoyl groups are twisted away from the attached naphthalene rin
The title compound, C 29 H 24 Br 2 , has crystallographic twofold rotation symmetry. The Br atom in the 2 position is disordered with the methyl group in the 6 position. The biphenyl bridge bond distance and the torsion angle between the rings are in good agreement with similar previously reported s
