| Abstract: | Synthesis, Properties, and Structure of Octameric Titanium Imide Chloride [Ti(NSiMe3)Cl2]8 The reaction of TiCl4 with N(SiMe3)3 in sealed glas-tubes yields the titanium imide chloride [Ti(NSiMe3)Cl2]8 ( 1 ). It crystallizes in the space group C2/c with a = 2 704.5(4), b = 1 303.9(1), c = 2 205.4(2) pm, β = 112.78(1)°, Z = 4. In 1 six Ti atoms are linked together by chloro and trimethylsilylimido bridges to form a ring structure. Two TiCl2-groups are bound in addition to the ring by two imido bridges. Upon annealing at 250°C 1 transformes to the isomeric polymer [Ti(NSiMe3)Cl2]n. Above 250°C 1 decomposes under separation of Me3SiCl affording TiNCl. |
