(Graphical Abstract) For the triclinic and monoclinic modifications of diastereomeric pinanyl sulfoxides co-crystal, remarkable alterations in unit cell parameters by transition from 293 to 150 were ascertained. Such alterations are accompanied by conformational restructuring of a stable hydrogen-bonded synthon from an "unfolded" to a "folded" form. The driving force of this restructuring is the tendency to form S=O.S=O interactions, which show up in the lowerature phases of both polymorphs. These are well-supported by the methods of quantum chemistry (DFT, B97-D/6-31G(d,p), AIM All).
