7,8-Dide­hydro-4,5-epoxy-17-methyl­morphinan-6-yl naphthalene-1-carboxyl­ate

The crystal structure of morphine 3-(1-naphthoate), (or 7,8-dide­hydro-4,5-epoxy-17-methyl­morphinan-6-yl naphthalene-1-carboxyl­ate), C₂₈H₂₅NO₄, was determined at 123 K. An intramolecular hydrogen bond exists between the secondary alcohol and the naphthoate group. Within the crystal structure, there is no significant π–π stacking, but there are significant intermolecular C—H...π interactions.

Special details

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

The absolute structure cannot be reliably determined therefore Friedel pairs have been merged.
