摘要：

The complexes [MoNCl3.DME] and [WNCl3.DME] (DME = 1,2-dimethoxyethane) have been prepared by the reaction of the nitride chlorides MNCl(3) with equimolar amounts of DME in CH2Cl2 suspensions. They form orange-red, moisture sensitive crystals, which are soluble in organic solvents. The molybdenum complex has been characterized by a crystal structure determination. Space group Pbca, Z = 8, structure solution with 1781 observed unique reflections, R = 0.031. Lattice dimensions at -60 degrees C: a = 738.6(1), b = 1182.2(1), c = 2314.1(1) pm. [MoNCl3 . DME] forms monomeric complexes with chelating DME molecules and Mo-O bond lengths of 215.4(4) and 247.4(4) pm, the longer one being in trans-position of the nitrido ligand. The MoN bond length of 163.3(5) pm suggests a triple bond.
