Abstract
Preparation and Structure of Alkali Penta-tert-butoxystannates(IV) Potassium, rubidium, and caesium tert-butoxide react with tin tetra-tert-butoxide in toluene to form compounds MSn(OtBu)5 [MK(2), Rb (3), Cs (4)] in contrast to lithium and sodium tert-butoxide. The compounds 2–4 are soluble in non-coordinating solvents and seem to be almost monomeric. 2 crystallizes as 2 · 1/2 toluene in the orthorhombic space group Fddd. The X-ray structure determination shows 2 to be coordinated as a helical polymer with the tin atom in the center of a trigonal bipyramid of tert-butoxide groups interlinked by two structurally different potassium atoms.
