摘要
Compounds with the general formula Cat(x)[Sc(H2O)(z)(SO4)(y)] - nH(2)O (Cat = NH4, H(2)Bipy (Bipy is 4,4'-bipyridine), and HEdp (Edp is ethylenedipyridine) are synthesized and identified by elemental analysis and IR spectral data. The X-ray diffraction analysis of (H(2)Bipy)[Sc(H2O)(SO4)(2)](2) center dot 2H(2)O shows that in the structure of this compound, the chains of ScO6 octahedra and SO4 tetrahedra are united to form ribbons due to the tridentate coordination of the sulfate ion. The ribbons form a framework, whose infinite cavities contain H(2)Bipy(2+) cations.
