Two lanthanide-oxo-cluster polymers were synthesized by hydrothermal reaction using Ln_2O_3 as initial lanthanide materials:[Ln_4(SO_4)_4(OH)_4(H_2O)_7]·_4H_2O(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(μ_3-OH)_4]~(8+) cations and SO_4~(2-) anions.The overall structure of 1 can be assigned to 6-connected pcu-type topology with the point symbol of(4~(12).6~3).
Two lanthanide-oxo-cluster polymers were synthesized by hydrothermal reaction using Ln_2O_3 as initial lanthanide materials: [Ln_4 (SO_4) _4 (OH) _4 (H_2O) _7] · _4H_2O (Ln = Er 1, Ho 2) , IR spectra, X-ray single-crystal diffraction, 2D IR correlation spectra and UV-visible absorption spectra. Single-crystal X-ray analyzes reveal those compounds 1 and 2 are isostructural, and 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 (μ_3-OH) _4] ~ (8+) cations and SO_4 ~ (2-) anions.The overall structure of 1 can be assigned to 6 -connected pcu-type topology with the point symbol of (4 ~ (12) .6 ~ 3).
