6,7,6',7'-Tetra-phenyl-2,2'-bi[1,3-dithia-5,8-diaza-cyclo-penta-[b]naphthalenyl-idene] chloro-form disolvate.

Project description:The title compound, C(42)H(24)N(4)S(4)·2CHCl(3), a symmetrical tetra-thia-fulvalene (TTF) derivative, was prepared by a tri-ethyl-phos-phite-mediated self-coupling reaction of 6,7-diphenyl-1,3-dithia-5,8-diaza-cyclo-penta-[b]napthalen-2-one. The asymmetric unit contains two TTF mol-ecules and four chloro-form solvent mol-ecules. Cl⋯Cl inter-actions [contact distances = 3.263 (1)-3.395 (2) Å] are present between the solvent mol-ecules, resulting in a tape along the bc plane. The crystal packing features weak C-H⋯Cl and C-H⋯N hydrogen bonds, resulting in the formation of a two-dimensional supramolecular network.

2,11-Dibromo-5,8-dibut-yl[4]helicene.

Project description:A racemic mixture of the title compound, C(26)H(26)Br(2), a brominated [4]helicene, crystallizes, forming columns of stacked mol-ecules. There are two crystallographically unique mol-ecules in the asymmetric unit, both with the same helical handedness. As is typical with helicene congeners, the unique mol-ecules show short inter-atomic contacts between H atoms at the fjord region, with H?H distances of 1.87 and 1.94?Å. Mol-ecules with the same helical handedness segregate in the crystal packing, forming homochiral columns. The stacked mol-ecules are piled in a column with alternate orientations. The shortest C?C distance in the stacked mol-ecules is 3.306?(4)?Å.
