 Title    N-Chlornitrenokomplexe des Wolframs: WC1 4 (NC1) und [CH 3 CN-WC1 4 (NC1)] N-Chloro-Nitrene Complexes of Tungsten: WC1 4 (NC1) and [CH 3 CN-WC1 4 (NC1)]  
 Abstract    WC1 4 (NC1) has been prepared as a red-brown crystal powder by the reaction of tungsten hexacarbonyl with excess nitrogen trichloride in boiling CC1 4 . The complex is associated via chloro bridges, forming dimeric units, according to the IR spectrum. Thermal decomposition at 200 °C leads to tungsten nitride trichloride, WNC1,. With acetonitrile, WC1 4 (NC1) reacts with formation of the monomeric complex [CH,CN-WC1 4 (NC1)], which was characterized by its IR spectrum as well as by an X-ray structure determination. Crystal data: space group P2,/m, Z = 2 (1387 independent observed reflexions, R — 0.07). Lattice dimensions at 20 °C: a = 590.4(3), b = 729.0(3), c = 1124.6(4) pm, ß = 100.63(2)°. The complex forms monomeric molecules, in which the tungsten atom has a distorted octahedral environment of four chlorine atoms in equatorial positions, and the acetonitrile molecule in fram-position to the W=N —Cl group. Bond lengths WN = 172 and NCI -161 pm; bond angle WNC1 = 175.5°.
