The open-framework coordination polymer Er(C9H9O6)(H2O)2·2.5H2O (C9H9O6 = cis,cis-1,3,5-cyclohexanetricarboxylate) has been synthesized under hydrothermal conditions. Each Er ion is coordinated to nine oxygen atoms belonging to two water molecules and five carboxylate ligands. Its 3-D polymeric structure possesses channels containing the guest water molecules that can be removed to afford a porous material Er(C9H9O6)(H2O)2. The metal−organic framework in Er(C9H9O6)(H2O)2 can withstand the removal of 1 equiv of coordinated water.
