Crystal structure of (±)-(7RS,8SR)-7-methyl-1,4-dioxaspiro[4.5]decane-7,8-diol
In the title compound, C(9)H(16)O(4), the five-membered dioxolane ring adopts a twist conformation; two adjacent C atoms deviate alternately from the mean plane of other atoms by −0.297 (4) and 0.288 (4) Å. The spiro-fused cyclohexane ring shows a chair form. The hydroxy group substituted in an ax...

Sumario: | In the title compound, C(9)H(16)O(4), the five-membered dioxolane ring adopts a twist conformation; two adjacent C atoms deviate alternately from the mean plane of other atoms by −0.297 (4) and 0.288 (4) Å. The spiro-fused cyclohexane ring shows a chair form. The hydroxy group substituted in an axial position makes an intramolecular O—H⋯O hydrogen bond with one of the O atoms in the cyclic ether, forming an S(6) ring motif. In the crystal, the O—H⋯O hydrogen bond involving the equatorial hydroxy group connects the molecules into a zigzag chain with a C(5) motif running along the c axis. |
