Abstract

By fine-tuning the reaction temperature to 5, 15, 30, and 50 °C, respectively, four different complexes, [Cd(HC4O4)2(H2O)4] (1), [Cd4(C4O4)4(H2O)16]•(H2O)2 (2), [Cd(C4O4)(H2O)2] (3), and [Cd(C4O4)(H2O)2] (4), were formed successfully from the identical initial reaction mixture. Moreover, an unprecedented reversible interconversion among the four complexes at the corresponding reaction temperatures mediated by the mother liquor was observed.
