6,7,6',7'-Tetraphenyl-2,2'-bi[1,3-dithia-5,8-diazacyclopenta[b]naphthalenylidene] chloroform disolvate

Abstract

The title compound, C₄₂H₂₄N₄S₄·2CHCl₃, a symmetrical tetrathiafulvalene (TTF) derivative, was prepared by a triethylphosphite-mediated self-coupling reaction of 6,7-diphenyl-1,3-dithia-5,8-diazacyclopenta[b]napthalen-2-one. The asymmetric unit contains two TTF molecules and four chloroform solvent molecules. Cl···Cl interactions [contact distances = 3.263 (1)-3.395 (2) Å] are present between the solvent molecules, 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.
