摘要：
Two lanthanide-oxo-cluster polymers were synthesized by hydrothermal reaction using Ln(2)O(3) as initial lanthanide materials: [Ln(4)(SO4)(4)(OH)(4)(H2O)(7)]center dot 4H(2)O (Ln = Er 1, Ho 2), and characterized by PXRD, IR spectra, X-ray single-crystal diffraction, 2D IR correlation spectra and UV-visible absorption spectra. Single-crystal X-ray analyses reveal that compounds 1 and 2 are isostructural, and they are both crystallized in the orthorhombic system Pccn space group. Compound 1 is a 3D lanthanide cluster polymer based on tetranuclear cubane-like [Er-4(mu(3)-OH)(4)](8+) cations and SO42- anions. The overall structure of 1 can be assigned to 6-connected pcu-type topology with the point symbol of (4(12).6(3)).
