The solid state structure of endo,endo-bicyclo[3.3.1]nonane-2,6-diol, rac-2, shows a hydrogen bonded, three-connected, chiral 3D-net with utg-topology, distinctively different from those formed by the so called tubuland diols, e.g. 2,6-dimethylbicyclo[3.3.1]nonane-exo2, exo-6-diol, rac-5, that crystallise as three-connected, chiral etanets and from the qtz-net formed by weaker hydrogen bonds in the bicyclo[3.3.1]nonane-2,6-dione, 3. The protected bicyclo[3.3.1]nonane2,6-dione, bis-2,6-ethylenedioxy acetal, 4, has a structure governed by weaker forces and can be interpreted as close packed stacks.
