Synthese und Kristallstruktur von Cl3Ti[N(SiMe2Cl)(SiMe2NH2)] / Synthesis and Crystal Structure of Cl3Ti[N(SiMe2Cl)(SiMe2N H2)]

Abstract

Cl3Ti[N(SiMe2Cl)(SiMe2NH2)] is yielded by reaction of TiCl4 with two molecules ClMe2SiNHSiMe3. A single crystal structure determination (P 21/n, a = 747.12(2), b = 1294.1(3), c = 1496.7(3) pm, β = 90.30(3)°, Z = 4) shows a planar four-membered ring Ti-N-Si-N as the central feature of the monomers formed by a weak coordinative bond of the NH2 group to the Ti atoms. The monomers are connected to give dimers via two Cl bridges linked to the Ti atoms.
