| 摘 要： | 六十年代后,缩二脲(以下简称配体B)与过渡金属等配合物的制备及物性测试已相继报道1]。但与稀土形成配合物的报道很少,A.Seminara2]等合成过镨、钕等氯化物与缩二脲的配合物。钪、钇的硝酸盐与缩二脲固体配合物的合成及其性质的研究尚未见报道。我们在无水乙醇介质中合成出ScB4(NO3)3和YB4(NO3)3固体配合物,并研究了它们的差热、红外光谱、摩尔电导及X-射线粉末衍射等性质。

| Abstract: | In this work, the solid complexes of scadium and yttrium nitrates with biuret have been synthesized in anhydrous ethanol medium. The composition of these complexes were determined as ScB4(NO3)3 and YB4(NO3)3 (where B = biuret) by the methods of elemental analysis, X-ray powder diffraction, electrical conductance measurement infrared spectrometer and DTA-TGanalysis. ScB4(NO3)3 and YB4(NO3)3 melt at 220℃ and 258℃ respectively, with decomposition. They are stadle in drv air. |
