| 摘要: 在乙醇一水混合溶液中,采用沉淀法制得了三十个苯基氧肟酸、正辛基氧肟酸与除钜以外的镧系元素及钇的配合物.通过元素分析、红外光谱、紫外光谱、质谱和差热热重分析研究了它们的组成和性质.它们的组成可分别确定为:M(C6H5C(O)NHO)3和M(n-C7H15C(O)NHO)3;光谱研究说明配体失去羟基质子后与希土离子形成了O、O五元螯合物,质谱和差热热重分析进一步说明螯合环在质子轰击与加热至220℃时均不易断裂,非常稳定. |

| Abstract: Thirty coordination compounds of lanthanidcs(except promcthium)and yttrium with bcnzohydroxamic acid(BHA), C6H5·CO·NHOH and n-octahydroxamic acid(OHA), n-C3H17CO·NHOH have been prepared by precipitation in cthanol-watcr mixture. By means of elemental analysis IR, UV, MS spectra as well as DT-TG analysis,the compositions and properties of these coordination compounds have been identified and characterized. They can be formulated as M[C6H5C(O)NHO]3(for BHA)and M[C7H15C(O)NHO]3(for OHA). The formation of O, O pcntacyclic chclatcs of rare earths with ligands after dissociating a proton of hydroxyl has been established by the spectra data. By means of the MS and DT-TG studies, it has been shown that the stable chclating ring would not be broken under both the proton bombarding and heating at 220℃. |
