We report on the structures of three dibromothiophene compounds ( 4 , 5 , and 12 ) and the analysis of the patterns of self‐assembly in the solid state by CBr⋅⋅⋅BrC halogen bonds of a selected set of 16 di‐ or poly‐bromine(poly)thiophene monomers sorted according to the dimensionality of their halogen‐bonded, extended frameworks thereby identifying syn ‐ or anti ‐strings and layers. We conclude that in 1 , 2 , 9 , and 10 , the antiparallel orientation of successive CBr⋅⋅⋅BrC halogen‐bonded dibromothiophene units along extended anti ‐strings is linked to the occurrence of solid‐state polymerization.
