Abstract: The nitridomolybdenum(VI) complexes MoITOI3 (OPPh^)p and [Bu4N] LMoUCl^j were synthesized from lioCl \ ^CCH^CN)^, sodium azid, triphenylphosphine oxide and totrabutylaromonium chloride respectively in acetonitrile. The reaction of fioClr with sodium azide and triphenylphosphine oxide also gave iioNCl ^ (OPPh^^j which is found to the anew way of preparing nitridomolybdenum complexes.The nitridomolybdenum complexes obtained were analytically pure. Attempts to synthesize nitridotungsten(VI) complexes by reaction of wCl ^ with sodium azide in acetonitrile gave impure WNC1^(CH^ON)^ complex. Reaction of the recrystallized and decomposition product of WNCl^(CHyOll)p with triphenylphosphine oxide in methylenechloride gave pure VfifCl^(0PPh^)2 in low yield. Similar reaction of ViWCl^(CH^CN)p with tetrabutylammonium chloride an.d 2,2'-dipyridyl in acetonitrile gave only impure products.
