Abstract

A Co(II) MOF {[Co₃(L)₂(H₂O)₄](DMF)₂}_n (1) and three Cd(II) MOFs [Cd₃(L)₂(H₂O)₇]_n (2), [Cd₃(L)₂(H₂O)₁₁]_n (3) and [Cd₃(L)₂(DMF)₂(H₂O)]_n (4) are synthesized based on the promising multifunctional tricarboxylate ligand 6-(3, 5-dicarboxyl phenyl) nicotinic acid (H₃L). 1 exhibits a 3D framework with 1D channels which contains opposite-handedness helical chains based on the trinuclear Co(II) clusters. 2–4 are obtained depend on different reaction conditions. 2 displays a 3D framework, which is composed of two kinds of 2D layers linked with each other. 3 shows a rare tongue-and-groove-type bilayer structure. And 4 is an interesting 3D framework containing infinite 1D inorganic Cd–O–Cd chains. In these MOFs, the H₃L ligand shows the versatile coordination modes and strong coordination ability. Furthermore, the magnetic and solid-state luminescent properties of the MOFs have been investigated.
