摘要
The nitrido complex (Me2PhP)(3)Cl2Re=N-ReCl4(PMe2Ph) results from the reaction of ReNCl2(PMe2Ph)(3) with GeCl4 in toluene. The mixed valent dinuclear complex is paramagnetic with mu(eff) = 1.96 B.M. at 300 K. It crystallizes with one solvate molecule as red crystals (Me2PhP)(3)Cl2Re=N-ReCl4(PMe2Ph). C7H8 with the space group P (1) over bar and a = 1075.4(6), b = 1330.5(6), c = 1745.3(11) pm, alpha = 101.20(3), beta = 105.88(3), gamma = 94.23(3)degrees, Z = 2. In the dinuclear complex one molecule ReNCl2(PMe2Ph)(3) coordinates with its nitrido ligand to a fragment ReCl4(PMe2Ph). The resulting nitrido bridge is asymmetrical with distances Re-N of 170.6(6) and 205.5(6) pm, and a bond angle Re1-N-Re2 = 174.6(3)degrees.
