(Figure Presented) An integrated study of the organic-inorganic framework material zinc cyclohexane trans-1,2-dicarboxylate involving synthesis,structure elucidation, computer simulation,and calorimetry shows that the chiral R,R form (right in picture) is less stable than its racemic R,R/S,S analogue (left) and adopts a layered structure with a fundamentally different topology. The results point to the possibility that the structural diversity of racemic frameworks and their homochiral analogues may be much greater than has hitherto been suspected.
