Abstract: The single crystal of the complex [Sc(NO3), (H3O)2[·(B15C5) has been prepared and characterized by elemental analyses, 1Rspectra and molar conductance. The structure of the complex is determined by X-ray single crystal diffraction analyses. The crystal of the complex is monoclinic, space group P21/n with cell parameters: a = 9.405(6), b=15.569(8), c= 15.896(2) Å,β = 95.92(1)°, V = 2315.5Å3,Z = 4, Dc = 1.538/cm3, D0= 1.54g/cm3. The structure has been refined to R = 0.051 and Rw = 0.055 using< 3172≥3σ(Ⅰ) observed data. Here the crown is not coordinated to the metal ion but is linked to the [Sc(NO3)3(H2O)2] molecule by O...H-O bonds. The Sc-Obond lengths are 2.158(3)-2.254(3) Å for nitrato-and 2.123(3)-2.143(3) Å for water oxygens.
