摘要

卤化锌与甲基脲（MeUr）在水溶液中以1:2的比例反应生成了新的配位化合物[Zn(MeUr)2Cl2]、[Zn(MeUr)2Br2]和[Zn(MeUr)2I2]。用x射线粉末衍射、红外光谱和单晶x射线衍射等方法对新配位化合物进行了分离和研究。研究了二甲基乙酰胺（DMA） [Zn(DMA)2Br2]对溴化锌配合物的多态修饰的结构。配合物具有分子四面体结构。计算得到卤化锌与甲基脲和二甲基乙酰胺配合物的偶极矩分别为9.3 ~ 9.7 D和6.6 ~ 8.2 D。

Syntheses, Crystal Structures, and Dipole Moments of Zinc Halide Complexes with Methylurea and Dimethylacetamide

Reaction of zinc halides with methylurea (MeUr) in 1 : 2 ratio in aqueous solution results in formation of new coordination compounds [Zn(MeUr)₂Cl₂], [Zn(MeUr)₂Br₂], and [Zn(MeUr)₂I₂]. The new coordination compounds have been isolated and studied by X-ray powder diffraction, IR spectroscopy, and single-crystal X-ray diffraction. The structure of previously unknown polymorphic modification of zinc bromide complex with dimethylacetamide (DMA) [Zn(DMA)₂Br₂] has been studied. The complexes have molecular tetrahedral structure. The dipole moments of the zinc halide complexes with methylurea and dimethylacetamide have been calculated to be of 9.3–9.7 D and 6.6–8.2 D, respectively.
