series of six-coordinate chloro Cr-III and V-III complexes involving crown ether, crown thioether and mixed ether/thioether crowns, [MCl3(crown)] (M = Cr or V, crown = 12-crown-4, 15-crown-5,18-crown-6, [12]aneS(4), [15]aneS(5), [9]aneS(2)O, [15]aneS(2)O(3), [18]aneS(3)O(3)) has been prepared by the reaction of [MCl3(thf)(3)] with rigorously dried crown in anhydrous CH2Cl2. In the presence of small amounts
一系列涉及冠醚、冠硫醚和混合醚/硫醚冠的六配位氯 Cr-III 和 V-III 配合物,[MCl3(crown)] (M = Cr 或 V,冠 = 12-crown-4, 15 -crown-5,18-crown-6, [12]aneS(4), [15]aneS(5), [9]aneS(2)O, [15]aneS(2)O(3), [18] ]aneS(3)O(3)) 是通过 [MCl3(thf)(3)] 与严格干燥的冠在无水 CH2Cl2 中反应制备的。在少量水的存在下,获得单水物质 [MCl3(H2O)(15-crown-5)] 和 [MCl3(H2O)(18-crown-6)]。产品已通过红外和紫外/可见光谱、微量分析和 [CrCl3(H2O)(18-crown-6)]、[VCl3(H2O)(15-crown-5)] 和 [CrCl3([15] aneS(5))],通过 X 射线晶体学。特别是
