Aliphatic dicarboxylates with three-dimensional metal–organic frameworks possessing hydrophobic channels

Abstract

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.
