在丙酮溶液中合成了两种未见报道的 4′-溴-5′-硝基苯并-15-冠-5(L)与硫氰酸钠、钾的固体配合物.对它们进行了元素分析、红外光谱、紫外光谱、差热、热重和 X-射线粉末衍射分析及摩尔电导的测定.红外光谱等结果表明—NO_2、—Br 未参与配位,而 SCN~-则以 N 作为配位原子,故可推测配合物中心离子的配位数为6.K~+与L 并非生成常见的夹心配合物,而是生成1:1型非溶剂合、不含水的固体配合物.
Two novel solid complexes of 4’-bromo-5’-nitrobenzo-15-crown-5 (L) with sodium and potassium thiocyanate were synthesized in acetone solution. Analysis, infrared spectrum, ultraviolet spectrum, differential thermal analysis, TG and X-ray powder diffraction analysis and determination of molar conductance.The results of infrared spectroscopy showed that -NO 2 and -Br did not participate in the coordination, while SCN ~ - Therefore, it can be inferred that the coordination number of the central ion of the complex is 6. K ~ + and L do not form common sandwich complexes, but generate solid complexes of 1: 1 non-solvent and non-aqueous.
