All non-H-atoms were refined with anisotropic thermal parameters with the exception of the disordered 3-pentyl side chain. Hydrogen atoms were placed in idealised positions and refined using a riding model. Site occupancy factors for disorderd groups were first refined and later fixed to the refined values. The newly implemented RIGU restraints were used during refinement. Bond-distances and bond-angle restraints were also used during refinement. The following is the output of checkCIF/PLATON routine on the .cif and .fcf files: REFNR01_ALERT_3_A Ratio of reflections to parameters is < 6 for a centrosymmetric structure sine(theta)/lambda 0.5003 Proportion of unique data used 1.0000 Ratio reflections to parameters 5.2963 THETM01_ALERT_3_A The value of sine(theta_max)/wavelength is less than 0.550 Calculated sin(theta_max)/wavelength = 0.5003 PLAT027_ALERT_3_A _diffrn_reflns_theta_full (too) Low ............ 15.00 Deg.

High-pressure data, these alerts are not unusual and are to be ascribed to the physical restrictions imposed by the pressure cell and limited access to reciprocal space. Data to parameter ratio was actually increased to 6.1 with the use of restraints. Data collected from the crystal in two orientations were merged together. PLAT157_ALERT_4_C Non-standard Monoclinic Beta Angle less 90 Deg 88.21 Deg. The non-standard setting was chosen to facilitate comparison with the structure predicted by theory.

PLAT031_ALERT_4_B Refined Extinction Parameter within Range ....2.333 Sigma The four strongest reflections show a systematic trend of Fo < Fc. In view of this and of the crystal growth conditions we believe refinement of an extinction parameter is meaningful. PLAT414_ALERT_2_C Short Intra D-H..H-X H4 .. H21A .. 1.98 Ang. Noted, no action taken. These distances are not exceedingly short. Some of these atoms are disorderd; it is possible that this distance is an artifact of refinement.

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. ; loop_ _geom_bond_atom_site_label_1 _geom_bond_atom_site_label_2 _geom_bond_distance _geom_bond_site_symmetry_2 _geom_bond_publ_flag S1 C9 1.754(6) . ?
