Die Kristallstruktur des Silicium(IV)-acetats

Abstract

The crystal structure of Si(OCOCH 3 ) 4 has been determined from single-crystal x-ray analysis. The compound crystallizes in the tetragonal space group P [unk]2 1 c . The unit cell with lattice constants a = 7.42, c = 11.34 Å contains two molecules. The crystals are built up by isolated silicon(IV) acetate molecules. The silicon atom is tetrahedrally coordinated and the acetate group has a role of monodentate ligand. The oxygen atom coordinated to silicon is at 1.625 Å while the second oxygen atom of the same acetate is 2.927 Å apart from silicon atom.
