报道了N-月桂酰吡咯烷(DOPOD)与硝酸铀酰形成的配合物晶体的合成、表征和结构.由元素分析及红外光谱确定了萃合物的组成UO_2(DOPOD)_2(NO_3)_2,该晶体属正交晶系,空间群为Pbca.配合物中铀酰离子由六个氧原子配位,其中四个来自硝酸根,另两个来自两个DOPOD配体.两硝酸根和两个DOPOD配体分别处于对位位置,形成以铀原子为中心的六方双锥结构.在构象上,两个DOPOD配体的长碳链及五元杂环处于顺式构象位置.
The synthesis, characterization and structure of the complex crystals of N-lauroyl pyrrolidine (DOPOD) with uranyl nitrate were reported.The composition of the complex, UO_2 (DOPOD) _2 (NO_3) _2, was determined by elemental analysis and infrared spectroscopy The crystal belongs to the orthorhombic system and the space group is Pbca. The uranyl ion in the complex is coordinated by six oxygen atoms, of which four are from nitrate and the other two are from two DOPOD ligands. Two nitrate and two DOPOD ligands are located in the para position respectively to form a hexagonal bipyramid structure centered on uranium atoms. In conformation, the long carbon chains and five-membered heterocycles of the two DOPOD ligands are in cis conformation.
