The 2:1 charge-transfer complex of 4,6-dimethyldibenzothiophene and 7,7,8,8-tetracyano-2,3,5,6-tetrafluoroquinodimethane

Abstract

The title compound, 2C14H12S·C12N4F4, was obtained by using 4,6-dimethyldibenzothiophene (DMDBT) as an electron donor and 7,7,8,8-tetracyano-2,3,5,6-tetrafluoroquinodimethane (F4TCNQ) as an electron acceptor. The asymmetric unit consists of one DMDBT molecule and one half of an F4TCNQ molecule, which lies on an inversion centre. In the crystal, the DMDBT and F4TCNQ molecules form a 2:1 unit via a charge-transfer interaction, with a centroid–centroid distance of 3.3681 (15) Å between the five-membered ring of DMDBT and the six-membered ring of F4TCNQ. An F...F contact [2.911 (1) Å] is also observed.
