Abstract

A conformationally locked C-2h symmetric tetrol concomitantly crystallized in two polymorphic modifications, differing principally in the mode of molecular association by C-H center dot center dot center dot O hydrogen bonds; the non-centrosymmetric tetragonal polymorph exhibits two complementary helical molecular arrangements mediated by O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds.
