| Abstract: | Two hydrogen-bonded supramolecular compounds having the general formula [M(H2O)6][H2L] (M=MnII or CoII and H4L=1,2,4,5-benzenetetracarboxylic acid), have been newly prepared by the reaction of [M(H2O)6](ClO4)2 and [C6H2(COOH)4] (H4L), and structurally characterized by X-ray diffraction. The metal center in each compound is six-coordinated, forming an ideal octahedral geometry. Both neutral formula units make unique three-dimensional supramolecular architectures through hydrogen bonds and stabilized by electrostatic force. |
