Summary[edit]
DescriptionCobalt complexes.jpg |
English: Illustration of autocomplex of CoCl2 in DMSO. The other 4 tubes are for comparison. From left to right: CoCl2 in H2O, CoCl2 in HCl (containing [CoCl4]2-), CoCl2 in DMSO, Co(ClO4)2 in DMSO (containing [Co(DMSO)6]2+) and Co(ClO4)2 in H2O. All cobalt salts are 0.5 mol/L and hexahydrated. CoCl2 reacts with DMSO to form an autocomplex: 2 CoCl2 + 6 DMSO ⇌ [Co(DMSO)6]2+ + [CoCl4]2-. The color of this solution is the mix color of [CoCl4]2- and [Co(DMSO)6]2+.
中文:CoCl2在DMSO中的自配位反应,另外四个离心管用作对比。从左到右:CoCl2的水溶液、CoCl2的浓盐酸溶液(含有[CoCl4]2−)、CoCl2的DMSO溶液、Co(ClO4)2的DMSO溶液(含有[Co(DMSO)6]2+)及Co(ClO4)2的水溶液。所用的溶液均为0.5 mol/L浓度,且金属盐为六水合物。CoCl2和DMSO反应生成自配合物: 2 CoCl2 + 6 DMSO ⇌ [Co(DMSO)6]2+ + [CoCl4]2-,该溶液的颜色是[CoCl4]2-和[Co(DMSO)6]2+的混合颜色。 |
