trans-1,2,3-Tris(1-hydroxycyclo­propyl)cyclopropane

The central three-membered ring in the title compound, trans-1,1',1''-cyclo­propane-1,2,3-triyl­tris­(cyclo­propanol), C₁₂H₁₈O₃, shows pronounced asymmetry of the bond lengths, which is induced by the different orientations of the substituents. A network of hydrogen bonds links the mol­ecules into sheets.
