The crystal structures of twelve different DL-malates have been determined and refined from singlecrystal X-ray diffraction data. In addition, powder diffraction data were used for the refinement of the lattice parameters, The title compounds are the neutral DLmalates Li2(C4H4O5) ž 2 H2O (space group P21/c), Mn(C4H4O5) ž 3 H2O (Pbca), Cd(C4H4O5) ž 3 H2O (P21/n), Sr2(C4H4O5)2 ž 5 H2O (P1¯) and Ba(C4H4O5) ž 2 H2O (P1¯) as well as the acid DL-malates RbH(C4H4O5) (Fdd2), CsH(C4H4O5) ž H2O (P21/n), MgH2(C4H4O5)2 ž 4 H2O (C2/c), CaH2(C4H4O5)2 ž 2 H2O (C2/c), ZnH2(C4H5O5)2 ž 4 H2O (C2/c), LiH3(C4H4O5)2 (P- 1), CsH3(C4H4O5)2 (P1¯). A comparison of DL-malate structures and a scheme of structural characterization according to cation polyhedra connection is proposed.
