Crystal structures and luminescent properties of two novel coordination polymers containing Ln3+ and SO42-

Two novel lanthanide-sulfate coordination polymers based on inorganic lanthanide-sulfate skeletons and chelidamic acid (H3CAM): {[Ln2(HCAM)2(H2O)2SO4] · 2.5H2O}n (Ln = Dy (1) and Tb (2)) have been synthesized under hydrothermal condition, which are 1D chains constructed by an intriguing bowl-like structure as the repeating unit.
