(Z,2R,3R,4aR,7R,12aS)-2,3,7,8,12,12a-Hexahydro-2,3-dimethoxy-2,3,7-trimethyl-4aH-[1,4]dioxino[2,3-c]oxecin-5(11H)-one (C16H26O6) crystallizes in the space group P31 and approximates the conditions necessary for diffraction symmetry enhancement without twinning for the hk ≠ 3N reflections. The structure may be described as an occupancy modulation of a 1:1 disordered P3121 parent structure with Z = 3 that would only contribute to the hk = 3N reflections. The crystal studied was a 0.717 (2):0.283 twin, but also had a stacking fault that on average caused the (1 − pj):pj population ratio for the alternative orientations of ordered columns along the three non-equivalent screw axes (j = 1, 2 or 3) of P31 to be describable by p1 = 0.068 (3), p2 = p3 = 0.960 (3). The effect of these stacking faults could be simulated using global parameters that modify an ordered prototype structure. The structure reveals that the ten-membered lactone ring incorporates a Z-configured double bond and that the methoxy-substituted stereogenic centers created during a trans-diol protection step each possess the R-configuration.

Comment top

The crystal is twinned. The structure could be solved by direct methods using the raw data and assuming no twinning, but would not refine below 10%. The constrained least squares refinement program RAELS2000 can account for twinning, pseudo-symmetry and stacking faults and was ideal for refining this structure.

In the crystallographic asymmetric unit there are three C16H26O6 molecules which are chemically identical and pseudo-symmetrically related. The crystal was a 0.716 (2): 0.284 twin and also had a stacking fault so that reflections with h − k ≠ 3 N had Fcalc scaled by 0.912 (3) compared to reflections with h − k = 3 N. Also 0.011 (1) of the structure is a disorder created by the same pseudo symmetry operator as the observed twin rule that relates the hkl and −k-h-l reflections. Full details of the refinement procedure are given in the accompanying report and in _refine_special_details of the crystallographic information file (CIF).

There were no outstanding features in the final difference electron density map.

Refinement. MGB045 C16H26O6

a = b 18.6850 (2), c 12.2359 (1) Å, a 90, b 90, g 120 °. Space group P31 Z = 9

The constrained least squares refinement program RAELS2000 was used for refinement. The crystal studied was a 0.716 (2): 0.284 twin and also had a stacking fault so that reflections with h − k ≠ 3 N had Fcalc scaled by 0.912 (3) compared to reflections with h − k = 3 N. Also 0.011 (1) of the structure is a disorder created by the same pseudo symmetry operator as the observed twin rule that relates the hkl and −k-h-l reflections.

The structure contains three columns of 31 symmetry in the unit cell along 1/3,2/3,z; 1,1, z; and 2/3,1/3,z related by the pseudo symmetry operation 5/3 − y,4/3 − x,1 − z. The structure can be described as an occupancy ordering of a 1:1 disordered parent structure in space group P3121 with one third the cell volume and Z = 3. A 2 fold axis is the disordering operation and the origin can be chosen so that this 2 fold axis passes through it. Ordering allows each column to take up one of the two orientations related by this two fold axis perpendicular to c. The resulting structure contains a pseudo two fold screw axis 5/3 − y, 4/3 − x, 1 − z relating the three moleculues in the asymmetric unit of P31. The atoms O17, O117, O217 lie approximately on this screw axis. The ordered structure has two columns in one orientation and the other column is in the alternative orientation. This creates diffraction symmetry enhancement without twinning for the h − k ≠ 3 N reflections should the pseudo 2 fold screw axis operations hold exactly. The 2: 1 ratio of columns in different orientations must be compromised in a twin disorder mechanism to explain the final refinement model which scaled the h- k ≠ 3 N reflections relative to the h- k = 3 N reflections and applied a twin-disorder rule relating the hkl and −k-h-l reflection intensities.

Various constraints were used in refinement to reduce the number of variables and allow the H atoms to be refined. Pseudo screw axis related O—Me and C—Me atom groups were constrained to have identical refineable geometries of exact local 3 m symmetry using refinable local orthonormal axial systems and refineable local orthoonormal axial systems (Rae, 1975). Non pseudo equivalent O—C and C—C distances were allowed to be independent. However only two sets of local coordinates were used for the methyl H atoms, one set for all methyls attached to an O atom, the other for the methyls attached to a C atom. All non H atoms had independent anisotropic atom displacement parameters and the H atoms were constrained to have the same parameters as the atom to which they were attached. Three sets of methyl H atoms, those attached to O20, O120 and O220 were allowed an extra common libration about the relevant C—H bond that was common to all 3 sets. These constraints allowed an essentially anisotropic refinement of all atoms using 707 variables for a reflection set of 5022 independent reflections with I >3σ(I) obtained after merging assuming P-3 diffraction symmetry.

The twinning reduced the difference between twin related reflection intensities by a factor of 0.432 compared to an untwinned crystal. The Rmerge for P-3 was 0.055 compared to 0.114 for P-31m diffraction symmetry. Data sets were collected for three different crystals and the crystal chosen for refinement was the one that had the best Rmerge for P-3 but the worst for P-31m. An initial structure solution was obtained by direct methods using SIR97 and space group P31. The handedness of the molecule was known and P31 rather than the inverted structure in P32 is appropriate.

Effect on Intensities of stacking faults

The structure can be described as three pseudosymmetry related columns as described above. The columns at 1/3,2/3,z amd 2/3,1/3,z are related by the translation 1/3(a − b).

If we say F1(h) is the stucture factor for a column at the origin and if we choose the origin along c so that a 2 fold rotation through the origin creates the alternative orientation for each column, then assuming only an occupancy modulation of a 1:1 disordered parent structure

F(h) = [(1-p1) + ω (1-p2) + ω* (1-p3)]F1(h) + [p1 + ω p2 + ω* p3]F1(2 h)

where ω = exp(2πi(h-k)/3) and (1-pj): pj gives the population ratio for the alternative orientations of a column. The perfectly ordered structure corresponding to our listed coordinates has p1, p2, p3 = 0,1,1. Values for p1, p2, p3 of 1,0,1 and 1,1,0 correspond to different origin choices. Structures related by a 2 fold rotation through the origin are obtained by swapping the values of (1-pj) and pj. Translational stacking faults of layers would preserve the value of p1 + p2 + p3.

When h − k ≠ 3 N F(h) = [p1 + ω p2 + ω* p3][F1(2 h) - F1(h)]

and F(2 h) = [p1 + ω* p2 + ω p3][F1(h) - F1(2 h)] so that

I(h) = I(2 h) = [p12 + p22 + p32 - p1p2 - p2p3 - p3p1]|F1(h) - F1(2 h)|2.

For a perfectly ordered structure I(h) = I(2 h) = |F1(h) - F1(2 h)|2 and F(h) = - F(2 h). It is possible to have diffraction symmetry enhancement and scaling without the need for twinning to describe these reflections should the pseudo symmetry operations hold exactly.

When h − k = 3 N F(h) = 3/2[F1(h) + F1(2 h)] + [p1 + p2 + p3 − 3/2][F1(2 h) - F1(h)]

and F(2 h) = 3/2[F1(h) + F1(2 h)] - [p1 + p2 + p3 − 3/2][F1(2 h) - F1(h)]

so that [I(h) + I(2 h)]/2 = 9/4|F1(h) + F1(2 h)|2 + [p1 + p2 + p3 − 3/2]2 |F1(2 h) - F1(h)|2

and [I(h) - I(2 h)]/2 = 6 [p1 + p2 + p3 − 3/2] [|F1(2 h)|2 - |F1(h)|2].

If we preserve the value of p1 + p2 + p3 as 2 then

F(h) = [F1(h) + 2 F1(2 h)] and F(2 h) = [2 F1(h) + F1(2 h)]

so that [I(h) + I(2 h)]/2 = 9/4 |F1(h) + F1(2 h)|2 + 1/4 |F1(2 h) - F1(h)|2

and I(h) - I(2 h)]/2 = ± 3 [|F1(2 h)|2 - |F1(h)|2].

Our first model refined a twin ratio (1 − q): q where q = 0.283 (2) and a separate scale for h − k ≠ 3 N reflections. The twinning to multiply I(h) - I(2 h)]/2 by 1 − 2q = 0.434 (4) rather than 1.0 implies a two fold screw axis perpendicular to c must be involved in creating a truly twin- disorder structure. The scaling of h − k ≠ 3 N reflection amplitudes by 0.896 (3) would imply the value of [p12 + p22 + p32 - p1p2 - p2p3 - p3p1] = 0.803 (6), i.e 0.8962, when averaged over twin related mosaic blocks. This is capable of many solutions and offers no further information.

This refinement assumed that p1 + p2 + p3 = 2 and makes 1/4|F1(2 h) - F1(h)]|2 to be just 10% of [I(h) + I(2 h)]/2 on average. Any disorder will probably make [p1 + p2 + p3 − 3/2]2 tend to zero. This model is refineable and was achieved using the model

I(h) = (1 − q)[(1-p) F(h) + p F(2 h)]2 + q[(1-p) F(2 h) + p F(h)]2,

where disorder parameter p and the twin parameter q are refinable using RAELS2000.

If we no longer use two scales we imply that there are no translational stacking faults. Such a refinement improves the data fit for h − k = 3 N but makes it worse for h − k 3 N and suggested that both types of stacking faults are present and two scales should still be used. This final model refined successfully and gave the results described in the summary at the beginning of this report.
