Polycatenated (4, 4) lanthanide(III) coordination networks based on apidate: Synthesis, structure and properties

Three rare earth coordination polymers, {[Ln2(μ3-ADI)2(μ2-ADI)(H2O)4]·H2O}n (Ln = Tb, 1; Eu, 2; Er, 3; ADI = adipate), which show the inclined interpenetration of (4, 4) nets and bright luminescence, were isolated from H2PDC-assisted (H2PDC = pyridine-2,3-dicarboxylatic acid) hydrothermal reactions of H2ADI and Ln2O3.
