چکیده
Single crystals of ScOH(CH3SO3)2 were obtained from a solution of Sc2(CO3)3 in methanesulfonic acid at pH 7. According to the X-ray single crystal structure determination, the compound crystallizes with the non-centrosymmetric orthorhombic space group Pmc21 (Z = 8, a = 743.92(8), b = 1497.7(3), c = 1540.1(2) pm, Rall = 0.0925) and contains the Sc3+ ions in octahedral coordination of oxygen atoms which belong to two OH− and four CH3SO3− ions. The linkage of the Sc3+ ions leads to chains according to the formulation ∞[Sc(CH3SO3)4/2(OH)2/2] which are oriented along the [100] direction and connected via hydrogen bonds. The IR spectrum of the compound shows the typical bands of the CH3SO3− ion.
