Molecular cocrystals of 5-(4-bromophenyl)-1,3,4-thiadiazol-2-amine: hydrogen bonding in the structures of the 1:1 adduct with 2-(naphthalen-2-yloxy)acetic acid and the salt with 3,5-dinitrobenzoic acid

G. Smith and D. E. Lynch

Synopsis: The cocrystal of 5-(4-bromophenyl)-1,3,4-thiadiazol-2-amine with 2-(naphthalen-2-yloxy)acetic acid is a 1:1 adduct, while with 3,5-dinitrobenzoic acid is a salt. In the adduct, hydrogen bonding gives a one-dimensional chain structure, and in the salt, a discrete centrosymmetric heterotetramer is formed

Formula: C8H6BrN3S·C12H10O3 and C8H7BrN3S+·C7H3N2O6-
