摘要
针对5f锕系金属配合物设计一系列[An~m(BH_4)_3(cis/trans-THF)_2](An=U、Np和Pu;m=Ⅲ和Ⅳ)配合物。采用相对论密度泛函理论广义梯度近似GGA-PBE泛函、TZP基组,在气态条件下优化得到12个配合物的几何结构,通过频率计算得到热力学参数和振动光谱,发现trans结构相对稳定。运用ADF程序计算得到THF溶液中的溶剂化能和电子结构,并对配合物的氧化还原电势进行系统的研究。
A series of[An~m(BH_4)_3(cis/trans-THF)_2](An=U,Np,Pu;m = Ⅲ and Ⅳ) complexes have been examined using relativistic density functional theory.12 structures were optimized to be energetically stable,and the trans-isomer shows lower in energy than the corresponding cis-one.Considering solvation and spin-orbit coupling effects,redox potentials of actinide complexes fromⅢ to Ⅳ were calculated.
