A new magnesium based metal-organic framework (MOF) [Mg-3(obb)(3)(H2O)(2)(DMA)(2)]center dot 2DMA (1; H-2-obb = 4,4'-oxybisbenzoic acid; DMA = N, N'-dimethyl acetamide) with Mg-3(H2O)(2)(DMA)(2)(COO)(6) secondary building units (SBUs) has been solvothermally synthesized and structurally characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and Elemental analysis (EA). A prominent feature of 1 is the unprecedented pillar-layered framework in which the obb ligand acts as both the linker and pillar simultaneously. In another way, The trinuclear Mg-3(H2O)(2)(DMA)(2)(COO)(6) subunit (SBU) can be simplified as 6-connected node and the flexible obb ligand acts as the linker. Correspondingly, the compound 1 exhibits 6-connected self-penetrated rob topology.
