Abstract

The homochiral coordination polymers [Cu-4(CH3OH)(H2O)(4)(Hbtb)(S-mal)(2)]center dot 4H(2)O and [Cu-4(CH3OH)(H2O)(4)(Hbtb)(R-mal)(2)]center dot 4H(2)O were synthesized by heating S- or R-malic acid (H(3)mal), 4,4',4 ''-benzene-1,3,5-triyltris(benzoic acid) (H(3)btb), and copper(II) acetate in an aqueous methanolic solution. The reaction with copper(II) nitrate in aqueous dioxane afforded the coordination framework [Cu-6(C4H8O2)(3)(H2O)(3)(btb)(4)]center dot 4C(4)H(8)O(2)center dot 10H(2)O, 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.
