2,6-Dimethylbicyclo(3.3.1)nona-3,7-diene-endo-2,endo-6-diol, an Alicyclic Diol Whose Crystal-Structure Involves Two Types of Hydrogen-Bonded Columns

Abstract

The crystal structure [C₁₁H₁₆O₂, C2/c, a 32.19(1), b 7.648(1), c 20.101(8)Ǻ, β 126.63(1)°, Z 16] of 2,6-dimethylbicyclo[3.3.1] nona 3,7-diene-endo-2,endo-6-diol (7) was determined with final R 0.041. This structure is unlike the helical and layer arrangements reported earlier for related alicyclic diols with C₂ symmetry, and is constructed from two types of double-stranded columns of diol molecules.
