Abstract
The crystal structure of 6-bromopeganol in a new polymorphic modification is found and determined by single crystal X-ray diffraction analysis. For the crystal structure of the new polymorph the formation of a centrosymmetric closed dimer (associate) is also characteristic. It consists of two bromopeganol molecules bound by centrosymmetric reciprocal hydrogen bonds O-H…N(1). This polymorph differs from the known one in the mutual arrangement and interaction of these associates.
