Reaction of (CpiPr4)2UI with NaN3 resulted in formation of tetrameric uranium(iii) azide-bridged 'molecular square' [(CpiPr4)2U(μ-η1:η1-N3)]4 (1). Addition of B(C6F5)3 to 1 induced loss of N2 at room temperature, yielding the uranium(v) borane-capped nitrido (CpiPr4)2U(μ-N)B(C6F5)3 (2).
（CpiPr4）2UI 与叠氮化钠反应生成了由叠氮桥联的四聚体铀（III）“分子正方形”[（CpiPr4）2U（μ-η1:η1-N3）]4（1）。在室温下向 1 中加入 B（C6F5）3 会导致 N2 逸出，生成硼烷封端的氮化物铀（V）（CpiPr4）2U（μ-N）B（C6F5）3（2）。
