Abstract

The homochiral coordination polymers [Cu4(CH3OH)(H2O)4(Hbtb)(S-mal)2]•4H2O and [Cu4(CH3OH)(H2O)4(Hbtb)(R-mal)2]•4H2O were synthesized by heating S- or R-malic acid (H3mal), 4,4′,4″-benzene-1,3,5-triyltris(benzoic acid) (H3btb), and copper(II) acetate in an aqueous methanolic solution. The reaction with copper(II) nitrate in aqueous dioxane afforded the coordination framework [Cu6(C4H8O2)3(H2O)3(btb)4]•4C4H8O2•10H2O, which does not contain chiral ligands. The compositions and crystal structures of the new compounds were determined by single-crystal X-ray diffraction and confirmed by X-ray powder diffraction, IR spectroscopy, thermogravimetric and elemental analysis.
