钪的直链聚醚配合物及其 NMR 波谱研究
Studies on the Synthesis and NMR of Scandium(Ⅲ)Complexes with Acyclic Polyethers
【摘要】 本文首次获得钪的直链聚醚配合物,发现共存阴离子不同对配合物组成与性质有显著影响.在高氯酸钪体系中得到双核及高电解质类型的配合物,利用测定13C NMR 自旋-晶格弛豫时间 T1等方法,证明所合成的配合物中钪与直链聚醚的配位氧原子直接结合及超过常见配位数为6的有意义结果.
【Abstract】 The new complexes of scandium (Ⅲ) chloride and perchlorate with some acyclicpolyethers have been synthesized and studied for the first time.The coordinationability of counterions effects greatly on the composition and property of complexes.Binuclear and high electrolyte type complexes have been found in scandium (Ⅲ)perchlorate system.It is of great interest to show that the complexes have highercoordination number than six generally found in literatures by method of 13C NMRspin-lattice relaxation time determination etc.
