_hbond_acceptor_comment          
;
In the cif file, there exists a "B alert" regarding the
O5-H5A without acceptor. The hydroxyl O5-H5A could have
formed a conventional intramolecular H-bond to the carbonyl
O4 (Fig. 5), however, the hydroxyl atom H5A points not to
the O4 atom but to the centroid of C11-C16 ring of the
neighboring translation-related molecule. It shows
that here the p-cloud of the C11*-C16* ring acts as the
acceptor of the O5-H5A, which can be verified
by the H-bond geometry H5A Cg and O5 Cg being
2.69 and 3.460(2)A, respectively, and the H-bond angle 161A.

;
Refinement of F^2^ against ALL reflections. The weighted R-factor wR and
goodness of fit S are based on F^2^, conventional R-factors R are based
on F, with F set to zero for negative F^2^. The threshold expression of
F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is
not relevant to the choice of reflections for refinement. R-factors based
on F^2^ are statistically about twice as large as those based on F, and R-
factors based on ALL data will be even larger.

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.
