Abstract
The title compound, [–Si(C12H9)2OSi(CH3)2O–]2, was
obtained unintentionally as the product of an attempted
crystallization of caesium bis(biphenyl-2,20-diyl)fluorosilicate
from dimethylformamide. In the crystal, the molecule is
located on an inversion center and the siloxane ring adopts a
twist-chair conformation with the two dimethyl-substituted Si
atoms lying 0.7081 (5) A ° out of the plane defined by the two
bis(biphenyl-2-yl)-substituted Si atoms and the four O atoms.
In each Si(C12H9)2 unit, the orientation of one terminal phenyl
ring relative to the phenylene ring of the other biphenyl
moiety suggests a parallel displaced – stacking interaction
[centroid distance = 4.2377 (11) A ° and dihedral angle =
15.40 (9) ].
