摘要：

Two unusual compounds, (C6H5NO2)(2)[La(H2O)(7)][CrMo6H6O24]center dot 10.5H(2)O 1 and (C2H5NO2)(2)[Nd(H2O)(5)][CrMO6H6O24]center dot 10H(2)O 2, have been synthesized and characterized by elemental analyses, IR, TG, and single crystal X-ray diffraction. Compound 1 is made up of supramolecular sheets of [Cr(OH)(6)Mo6O18](3-) polyoxoanion-supported lanthanum complexes pillared by individual [Cr(OH)(6)Mo6O18](3-) clusters via weak intermolecular interactions forming a three-dimensional microporous framework with two types of channels, and the 'guest' water molecules reside in the channels, Compound 2 also exhibits a new three-dimensional supramolecular network with one-dimensional sandglass-like channels based on the extensive hydrogen-bonding interactions between the [Cr(OH)(6)Mo6O18](3-) polyoxoanions and neodymium-glycine coordination complexes.
