The reaction between UI4 and triphenylarsine oxide (tpao) has been studied in non-aqueous solution. A number of solid complexes have been isolated, viz. α-UI4tpao2, β-UI4tpao2, UI4tpao4 and UI4tpao6. The room temperature stable UI4tpao2 (α form) proved not to be the trans-octahedral species as commonly found for UCl4 and UBr4, but an auto- ionized solid, viz. [UI2tpao4] [UI6]. The properties of these
在非
水溶液中研究了UI 4与三苯ar氧化物(
TPAo)之间的反应。已经分离出许多固体复合物。α-UI 4

TPAO 2,UI 4
TPAO 4和UI 4
TPAO 6。事实证明,室温下稳定的UI 4
TPAo 2(α形式)不是UCl 4和UBr 4常见的反八面体物种,而是一种自动电离的固体,即。[UI 2
TPAo 4 ] [UI6 ]。对这些物种的特性进行了讨论,并与它们的
氯代和
溴代类似物进行了比较。
