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

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
