Potassium chlorido­tris­(hypersil­oxy)aluminate dimer

The tris­(tri­methyl­silylsiloxide) ligand, also known as hypersiloxide, is an extremely bulky group. In an attempt to make the monomeric Al(OSi(SiMe₃)₃)₃, AlCl₃ was combined with 3 equiv. of potassium hypersiloxide. The title compound, a KCl adduct of aluminium tris­(hypersilyloxide) that is dimerized through a planar K₂Cl₂ ring, was isolated.

Special details

Geometry. 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.
