Twisted and half-chair conformations are found for the five- and six-membered rings comprising the fused-ring system in the title isoaltholactone derivative. In the molecular packing, linear supramolecular chains sustained by hydroxy-O—H

N(amine) hydrogen bonding are evident.

Special details top
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds involving l.s. planes. |
