资源简介：
Two novel chiral lanthanide–sulfate frameworks,
Ln4(OH)4(SO4)4(H2O)3 [Ln = Y (1) and Er (2)],
have been synthesized under hydrothermal reactions. X-ray crystal
structure analyses reveal that 1 and 2 are
isomorphous and crystallize in the orthorhombic space group P2(1)2(1)2(1). Both compounds are isostructural and contain
helical tubes and channels constructed from double left- and right-handed
helical chains. Further structural analysis reveals that compound 1 is a high connected binodal net by assigning the SO42– anion as a three-connected node and the
{Y4} cluster as a 12-connected node. Furthermore, the infrared,
thermogravimetric analysis, and powder X-ray diffraction properties
were also studied.
