ScOH(CH3SO3)(2), a basic methanesulfonate of scandium with chain structure

摘要

Single crystals of ScOH(CH3SO3)(2) were obtained from a solution of Sc-2(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 Pmc2(1) (Z = 8, a = 743.92(8), b = 1497.7(3), c = 1540.1(2) pm, R-all = 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 (1)(infinity)[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.
