In the orthorhombic crystalline phase of the title compound, C 20 H 11 I 2 NO 2 , all the benzene rings are parallel, whereas the acridine systems are either parallel or perpendicular to each other; this generates a herring-bone pattern. The acridine systems and benzene rings are inclined at an angl

The title compound, C 13 H 10 Br 2 O 2 , was obtained during the synthesis of azulene derivatives. There are two independent molecules in the asymmetric unit. The azulene frameworks of the molecules are planar, with mean deviations of 0.01 and 0.02 A Ê from the ring planes.
In the title compound, C 21 H 17 NO 4 S, all bond lengths and angles show normal values. The sulfonyl-bound phenyl ring forms a dihedral angle of 88.31 (1) with the mean plane of the carbazole fragment. The crystal packing is stabilized by weak intermolecular -, C-HÁ Á Á and C-HÁ Á ÁO interactions.
The title compound, C 13 H 10 ClN 5 O 2 , crystallizes with two molecules in the asymmetric unit. These are connected by ®ve hydrogen bonds, viz. three NÐHÁ Á ÁN interactions, two longer C OÁ Á ÁÁHÐN interactions, bifurcated at the O atom, and a CÐHÁ Á ÁN contact.
