通过Mo_2F_2与Me_3SiN_3在SO_2溶液中的氟-叠氮交换反应制备了钼（VI）和钨（VI）二叠氮化合物MO_2（N_3）_2（M=Mo，W）。在乙腈溶液中，氟化物-叠氮化物交换导致分离加合物MO 2（N3）2·2CH 3CN。MO 2（N3）2与2，2 '-联吡啶（bipy）反应生成联吡啶加合物（bipy）MO 2（N3）2。（bipy）MoO_2（N_3）_2水解生成[（bipy）MoO_2N_3]_2O。四叠氮阴离子[MO 2（N3）4]（2-）是由MO 2（N3）2与2当量的离子叠氮化物反应得到的。大多数钼（VI）和钨（VI）二氧代叠氮化合物的特征在于它们的振动光谱、冲击、摩擦和热敏性数据，并且在（bipy）MoO 2（N3）2、（bipy）WO 2（N3）2、[PPh 4]2[MoO 2（N3）4]、[PPh 4]2[WO 2（N3）4]和[（bipy）MoO 2N 3] 2 O的情况下，特征在于它们的X射线晶体结构。
Molybdenum(VI) and tungsten(VI) dioxodiazide, MO2(N3)2 (M=Mo, W), were prepared through fluoride-azide exchange reactions between MO2F2 and Me3SiN3 in SO2 solution. In acetonitrile solution, the fluoride-azide exchange resulted in the isolation of the adducts MO2(N3)2⋅2 CH3CN. The subsequent reaction of MO2(N3)2 with 2,2'-bipyridine (bipy) gave the bipyridine adducts (bipy)MO2(N3)2. The hydrolysis of (bipy)MoO2(N3)2 resulted in the formation and isolation of [(bipy)MoO2N3]2O. The tetraazido anions [MO2(N3)4](2-) were obtained by the reaction of MO2(N3)2 with two equivalents of ionic azide. Most molybdenum(VI) and tungsten(VI) dioxoazides were fully characterized by their vibrational spectra, impact, friction, and thermal sensitivity data and, in the case of (bipy)MoO2(N3)2, (bipy)WO2(N3)2, [PPh4]2[MoO2(N3)4], [PPh4]2[WO2(N3)4], and [(bipy)MoO2N3]2O by their X-ray crystal structures.
