Two three-dimensional open-framework metal dicarboxylates possessing channels with a hydrophobic environment have been synthesized. One is a malonate of the formula, [Cd(O2C-CH2-CO2)(H2O)]·H2O, I, and the other a glutarate of the formula [Mn(O2C-(CH2)3-CO2)], II. The three-dimensional structure of I is attained through infinite Cd–O–Cd corner-linkages. On the other hand, II, contains Mn–O–Mn layers cross-linked by MnO6 octahedra and glutarate moieties.
