The reaction of TiCl4 with N(SiMe3)3 in sealed glas-tubes yields the t
itanium imide chloride [Ti(NSiMe3)Cl2]8 (1). It crystallizes in the sp
ace group C2/c with a = 2704.5(4), b = 1303.9(1), c = 2 205.4(2) pm, b
eta = 112.78(1)-degrees, Z = 4. In 1 six Ti atoms are linked together
by chloro and trimethylsilylimido bridges to form a ring structure. Tw
o TiCl2-groups are bound in addition to the ring by two imido bridges.
Upon annealing at 250-degrees-C 1 transformes to the isomeric polymer
[Ti(NSiMe3)Cl2]n. Above 250-degrees-C 1 decomposes under separation o
f Me3SiCl affording TiNCl.
