Di-μ₂-chloro-di­chloro­di-μ₃-oxo-octa­phenyl­tetratin di­chloro­methane solvate

The title compound [systematic name: 1,2;3,4-di-μ-chloro-1,4-di­chloro-1,1,2,2,3,3,4,4-octa­phenyl-di-μ₃-oxo-tetratin(IV)], [Sn₄(C₆H₅)₈Cl₄O₂], crystallizes as a CH₂Cl₂ solvate. Unlike the previously known unsolvated form, the structure does not possess a crystallographic inversion center. The dimer consists of a central Sn₂O₂ ring with two additional adjacent Sn₂ClO four-membered rings. The Sn, O and Cl atoms are approximately coplanar; the Sn atoms exhibit a distorted trigonal-bipyramidal configuration.

Special details

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.
