摘要

Two Cd-Co heterometallic frameworks based on the ligand methylenesuccinate acid (H(2)MSA), three-dimensional (3D) [CdCo6(MSA)(6)(mu(3)-OH)(2)(H2O)(2)]center dot H2O (1) and one-dimen-sional (1D) [CdCo(MSA)(2)(H2O)(5)]center dot 3H(2)O (2), were synthesized at 120 degrees C and room temperature, respectively. Complex 1 has a 3D structure composed of an octahedral [CdO6] node and a 2D [Co-6] layer unit featuring a coedge hexagonal metal skeleton, and 2 displays a 1D chain structure with Cd2+ and Co2+ ions bridged by the MSA(2-) ligands. The 3D and 1D structures could transform into each other reversibly in the mother solution by controlling the temperature at room temperature and 120 degrees C, respectively. This phenomenon was analyzed in detail and could be well explained dynamically. Magnetic studies suggest the reversible transformation between 1 and 2 is along with switchable "on-off" spin-canted antiferromagnetism.
