Abstract

A series of microporous lanthanide coordination polymers containing p-dicarboxylate carborane ligand (1-8) have been synthesized from the reactions of 1,12-dihydroxycarbonyl-1,12-dicarba- closo-dodecaborane (p-CDCH ₂) with rare earth metals. Based on the well-known effect of lanthanide contraction, three distinct structure types were isolated: Structure type I crystallizes in the triclinic space group P1̄ with formula {[Ln ₂(p- CDC) ₃S ₆]·χS} _n (S=solvent molecules, such as H ₂O, MeOH, and DMF), Ln=Yb ³⁺ (1), Y ³⁺ (2), Tb ³⁺ (3), Gd ³⁺ (4), Sm ³⁺ (6) and structure type II also crystallizes in the triclinic space group P1̄ with formula {[Eu ₂(p-CDC) ₃(MeOH) ₂(H ₂O) ₄]·[Eu ₂(p-CDC) ₃(H ₂O) ₄-(DMF) ₂]·2DMF} _n (5). Nevertheless, structure type III crystallizes in the monoclinic space group P21/n with formula {[Ln ₂(p-CDC) ₃(MeOH) ₄(DMF) ₂]·2 MeOH} _n, Ln=Ce ³⁺ (7) and La ³⁺ (8). The structures of type I polymers consist of four-connected 2D lamellar networks, but type II and type III polymers are composed of six-connected 3D structures. Gas sorption property of compound 1' was studied, which showed selective CO ₂ capture over CH ₄ and N ₂.
