 Title    Synthese und Kristallstruktur des Imidokomplexes {TaCl4NC(Ph)[N(SiM e3)2]}2 * 2 C H 2C 12 Synthesis and Crystal Structure of the Imido Complex {TaCl4NC(Ph)[N(SiM e3)2]}2 * 2 C H 2C12  
 Abstract    The title com pound has been prepared by the reaction of N ,N,N '-tris(trim ethylsilyl)benz-amidine with tantalum pentachloride in C H 2CL suspension, forming am ber-coloured, moisture-sensitive crystals, which were characterized by an X-ray structure determ ination. Space group P 2,In, Z = 2, 4895 observed independent reflexions, R = 0.059. Lattice dimensions (— 65 °C): a — 1165.2(6), b -1335.4(6), c = 1629.0(7) pm, ß -93.23(4)°. The complex forms centrosymmetric molecules dimerized via chloro bridges TaCLTa with TaCl bond lengths of 247.2(2) and 277.1(2) pm, the longer one being in frarcs-position to the imido group, which can be formulated a sT * a= $ = C < *M (bond len g th sT a= N = 183.5(8), C = N = 134(1) pm. bond angle TaNC = Ph 162.7(7)°).
