The tris-(tri-methyl-silylsiloxide) 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 crystalline product isolated (40% yield), namely di-µ3-chlorido-bis-[µ2-tris-(tri-methyl-sil-yl)silanolato]tetra-kis-[tris-(tri-methyl-sil-yl)silanolato]dialuminium-dipotassium, [Al2K2Cl2(C19H27OSi4)6], is a KCl adduct of aluminium tris(hypersilyloxide) that is dimerized through a planar K2Cl2 ring, with K-Cl distances of 3.1131â
(8) and 3.319â
(3)â
Å, and ring angles of 77.41â
(2) and 102.60â
(2)°. This ring is on an inversion center, and there is no supra-molecular coordination.
