A new polymorph of diphenyl­bis(triphenyl­silyl)silane, C48H40Si3, has been discovered. Until now, only an ortho­rhom­bic polymorph of the title compound was known. The newly found trigonal polymorph crystallizes in R\overline{3} with one mol­ecule in the asymmetric unit.

Alert level A PLAT601_ALERT_2_A Structure Contains Solvent Accessible VOIDS of . 965.00 A   3
Author Response: There are channels along the c-axis in the structure which might contain (disordered) solvent. However, the highest peak in the difference map is significantly below 1e/A^3^ and as a result of that, the nature of the solvent could not be identified, not to mention a refinement.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

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 > σ(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.
