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.
