Abstract

Two porous metal-organic frameworks [Co(Tt)₂][Cu₄(D-cam)₄]·5H₂O·DMF (1; Tt = tris(triazolyl)borate, D-H₂cam = d-(+)-camphoric acid or (1R,3S)-1,2,2-trimethyl-1,3-cyclopentanedicarboxylic acid) and [Co(Tt)₂][Cu₄(L-cam)₄]·5H₂O·2DMF (2; L-H₂cam = l-(-)-camphoric acid or (1S,3R)-1,2,2-trimethyl-1,3-cyclopentanedicarboxylic acid) were prepared by mixing Cu²⁺, Co(Tt), and camphoric acid under solvothermal conditions. The structures of 1 and 2 reveal that the two-dimensional layers composed of chiral ligands and Cu-Cu paddlewheel units are connected through the metalloligands to form three-dimensional networks. It is noted that these solids show multifunctional properties such as gas adsorption onto the pores of the frameworks, antiferromagnetic coupling between spin carriers, and a small enantioselective separation of racemic alcohols.
