Comment On "Trimorphs Of 4-Bromophenyl 4-Bromobenzoate. Elastic, Brittle, Plastic" By S. Saha And G. R. Desiraju, Chem. Commun., 2018, 54, 6348

A re-refinement of the published but chemically implausible, crystal structure of "Form III" of 4-bromophenyl 4-bromobenzoate shows that it is not a polymorph, but instead a co-crystal containing both 4-bromophenyl 4-bromobenzoate (approximate to 25%) and likely 4-bromophenyl 4-nitrobenzoate (approximate to 75%).
