Figure 7
Ellipsoid plot for the refinement in the monoclinic pseudocell of the data collected at 90 K from a 1:1 co-crystal of rac-1,2-CHD and TPPO grown from acetone. While some of the ellipsoids are just a little larger than might be expected for a crystal studied at 90 K, none is especially large or eccentric. Deviations from monoclinic symmetry increase as the temperature is lowered and are largest for crystals grown from acetone, so the displacement ellipsoids (50% probability level) for the other five C2/c refinements are even less affected by the inappropriate averaging than those shown here. H atoms have been omitted for the sake of clarity. All atom labels can be worked out from those shown; atoms in the two independent sets of molecules (not shown in this drawing) are distinguished by an A or B at the end of the label. Molecule A is closer to y = ¼ while molecule B is closer to y = ¾.
