A 2:1 co-crystal of 3,5-di­bromo-4-cyano­benzoic acid and anthracene

The title co-crystal, C(8)H(3)Br(2)NO(2)·0.5C(14)H(10), was self-assembled from a 2:1 mixture of the components in slowly evaporating di­chloro­methane. The mol­ecules adopt a sheet structure parallel to (1-12) in which carb­oxy hydrogen-bonded dimers and anthracene mol­ecules stagger in both dimens...

Sumario:The title co-crystal, C(8)H(3)Br(2)NO(2)·0.5C(14)H(10), was self-assembled from a 2:1 mixture of the components in slowly evaporating di­chloro­methane. The mol­ecules adopt a sheet structure parallel to (1-12) in which carb­oxy hydrogen-bonded dimers and anthracene mol­ecules stagger in both dimensions. Within the sheets, six individual cyano acid mol­ecules surround each anthracene mol­ecule. Cyano acid mol­ecules form one of the two possible R (2) (2)(10) rings between neighboring cyano and bromo groups. Compared to the di­chloro analog [Britton (2012 ▸). J. Chem. Crystallogr. 42, 851–855], the dihedral angle between the best-fit planes of acid and anthracene mol­ecules has decreased from 7.1 to 0.9 (2)°.
