Stable Analogs of the Uranyl Ion Containing the −NUN− Group
摘要:
A series of compounds containing the -N=U=N- group has been prepared. Their physical and chemical properties are reported. They adopt a trans configuration, and are thermally robust. The chemistry of some recently-prepared O=U=N- compounds is also described. These are the first examples of stable analogs of the uranyl ion UO22+. The factors that determine their stability are discussed.
