چکیده
In the mol-ecule of the title compound {systematic name: 3-[2-(6-hydr-oxy-5-hydroxy-methyl-5,8a-dimethyl-2-methyl-ene-per-hydro-1-napth-yl)-1-(nitro-meth-yl)eth-yl]-2(4H)-furan-one}, C(21)H(31)NO(6), the cyclo-hexane rings have chair conformations. Intra-molecular O-H⋯O hydrogen bonding results in the formation of a six-membered non-planar ring with a twist conformation. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into infinite chains along the c axis.
