Bis­(tri­phenyl­stannyl)­borate toluene solvate

The title compound, [Sn₂(C₆H₅)₆(BHO₃)]·C₇H₈ or (Ph₃SnO)₂B(OH)·C₇H₈, is an unexpected diester produced during an attempted recrystallization of (Ph₃Sn)₃B₃O₃. A planar central B atom is coordinated to two Ph₃Sn groups through ester linkages, and to a hydro­xide group.

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.
