Abstract

Synthesis, IR spectroscopic and X-ray structural studies of new chlorine-containing uranyl complexes (C₁₀H₁₆N)₂[UO₂Cl₄] (I) and (C₁₃H₂₂N)₂[UO₂Cl₄]_0.5[UO₂(NO₃)₂Cl₂]_0.5 (II) have been carried out. Uranium-containing groups in structures I and II are [UO₂Cl₄]^2– complexes belonging to the crystal chemical group AM¹₄ (A = UO₂²⁺, M¹ = Cl^–),, which in II coexist with mononuclear complexes [UO₂(NO₃)₂Cl₂]^2–, which have a crystal chemical formula AB⁰¹₂M¹₂ (A = UO₂²⁺, B^{01 =} NO₃^–, M¹ = Cl^–). The features of intermolecular interactions in the structures of crystals I and II are considered with the help of molecular Voronoi–Dirichlet polyhedra.

摘要

新型含氯铀酰配合物 (C ₁₀ H ₁₆ N) ₂ [UO ₂ Cl ₄ ] ( I ) 和 (C ₁₃ H ₂₂ N) ₂ [UO ₂ Cl ₄ ] _{0.5 的}合成、红外光谱和 X 射线结构研究[UO ₂ (NO ₃ ) ₂ Cl ₂ ] _0.5 ( II)已进行。结构I和II中的含铀基团为 [UO ₂ Cl ₄ ] ^2–属于晶体化学组 AM ¹ ₄ (A = UO ₂ ²⁺ , M ¹ = Cl ^– ) 的配合物，在II 中与单核配合物 [UO ₂ (NO ₃ ) ₂ Cl ₂ ] ^2-共存，后者具有晶体化学式AB ⁰¹ ₂ M ¹ ₂ (A = UO ₂ ²⁺ , B ^{01 =} NO ₃ ^– , M ¹ = Cl ^– )。晶体结构中分子间相互作用的特征Ⅰ和II是在分子 Voronoi-Dirichlet 多面体的帮助下考虑的。
