Lanthanide coordination polymers [LnL(DMF) 2]·0.25H 2O [Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8), Dy (9), Ho (10), Er (11), and Tm (12)], and [GdL(H 2O) 3] (7′) (H 3L = 5-(4-carboxy-2-nitrophenoxy)- isophthalic acid), have been synthesized under hydro- and solvothermal conditions, respectively. Compounds 1-12 exhibit the same three-dimensional (3D) architecture, which is built up from binuclear paddle-wheel building blocks, and their resulting frameworks can be rationalized as rarely reported flu-3,6-C2/c topology. Compound 7′ crystallizes in the monoclinic system, space group P2 1/c. The ligands (L) bridge the Gd(iii) centers to form 3D frameworks featuring a zeolite BCT topology, which have been unreported based on rare earth metals until now. Moreover, compound 6 exhibits characteristic red luminescent properties of Eu(iii) complexes. The magnetic susceptibilities, over a temperature range of 2.0-300 K, of 7 and 7′ have also been investigated.
