Abstract

NaUO₂(mia)₃ (I) crystals (mia: monoiodacetate ion CH₂ICOO⁻) were synthesized and studied by X-ray diffraction and IR spectroscopic analyses. Uranyl-containing complexes [UO₂(mia)₃]^– in the structure correspond to the crystal chemical formula A(B⁰¹)₃, where A = UO₂²⁺, B⁰¹ = mia. Using coordination sequences, we analyzed the features of the 3D framework, which is realized in the structure of crystals of I and contains 8 crystallographically nonequivalent U or Na atoms. A semiempirical calculation and comparison of the calculated and experimental vibration frequencies in the IR spectrum of I were performed.

三（单碘乙酰氧基）尿酸钠的结构和红外光谱研究

摘要合成了 NaUO2(mia)3 (I) 晶体（mia：单碘乙酸根离子 CH2ICOO-），并通过 X 射线衍射和红外光谱分析对其进行了研究。含铀配合物 [UO2(mia)3]- 的结构对应于晶体化学式 A(B01)3，其中 A = UO22+，B01 = mia。我们利用配位序列分析了三维框架的特征，该框架是在 I 晶体结构中实现的，包含 8 个晶体学上不等价的 U 原子或 Na 原子。我们进行了半经验计算，并比较了 I 的红外光谱中的计算振动频率和实验振动频率。
