Crystals were mounted on a loop using oil then placed on the diffractometer under a nitrogen stream at 210K.
The crystal is twinned. The two components of the twin were separated using CELL_NOW and differ from each other by a 2º rotation around the axis 1.0 -0.11 -0.21 in real space. The resulting P4P file was used to integrate each domain simultaneously and the resulting P4P with the refined orientations of each domain was recycled to repeat the integration. After two times of this the resulting intensities were separated with TWINABS and the file with the averaged intensities (TWIN4.HKL) was used for 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 > 2σ( 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.
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. Table 2. Atomic coordinates ( x 104) and equivalent isotropic displacement parameters (Å2x 103) for MSW11 (CCDC 787543). U(eq) is defined as the trace of the orthogonalized Uij tensor. ________________________________________________________________________________ x y z Ueq ________________________________________________________________________________ K(1) 6922(1) 4014(1) 2797(1) 45(1) K(2) 3724(1) 4722(1) 986(1) 49(1) P(1) 3763(1) 3938(1) 2809(1) 41(1) P(2) 6789(1) 5148(1) 886(1) 44(1) O(1) 2393(3) 6950(2) 1327(1) 85(1) O(2) 6706(2) 5876(2) 3664(1) 55(1) O(3) 7793(2) 2256(2) 3916(1) 70(1) N(1) 6123(2) 2157(2) 1898(1) 33(1) C(1) 3619(3) 2363(2) 3025(1) 36(1) C(2) 2978(3) 1912(3) 3670(2) 46(1) C(3) 2923(3) 700(3) 3815(2) 56(1) C(4) 3508(3) -165(3) 3315(2) 62(1) C(5) 4156(3) 220(2) 2680(2) 49(1) C(6) 4230(3) 1445(2) 2530(2) 36(1) C(7) 4962(3) 1760(2) 1827(2) 34(1) C(8) 4505(3) 1613(2) 1126(2) 42(1) C(9) 5237(3) 1863(2) 485(2) 44(1) C(10) 6419(3) 2268(2) 555(2) 39(1) C(11) 6827(3) 2396(2) 1271(2) 32(1) C(12) 8130(3) 2766(2) 1402(1) 32(1) C(13) 8239(3) 4012(2) 1232(1) 32(1) C(14) 9466(3) 4279(2) 1441(1) 40(1) C(15) 10475(3) 3410(3) 1792(2) 42(1) C(16) 10349(3) 2211(3) 1951(2) 45(1)

Special Refinement Details Crystals were mounted on a loop using Paratone oil then placed on the diffractometer under a
nitrogen stream at 100K. The crystal contains solvent of crystallization. This solvent appears as rings stacked edge on
along the a-axis and through 0, ½ , ½. The solvent was modeled as benzenes (isotropic and constrained to ideal hexagons) stacked edge to edge between the inversion centers, requiring half occupancy.
