Abstract

2-Bromo-1,3-bis[2-(2-naphthyl)vinyl]benzene benzene hemisolvate, C(30)H(21)Br·0.5C(6)H(6), (I), with two formula units in the asymmetric unit, exists in the crystal structure in a conformation in which the trans (2-naphthyl)vinyl substituents on the central bromobenzene moiety appear as nearly fully extended `wings', while 9-bromodinaphth[1,2-a:2',1'-j]anthracene, C(30)H(17)Br, (II), adopts a highly nonplanar `manta-ray' shape, with the H atoms in the interior of the molecule within van der Waals contact distances. The packing of the significantly twisted molecules of (I) generates large voids which are filled by benzene solvent molecules, while molecules of (II) stack compactly with all C-Br bonds parallel within the stack.
