Studies of the gas sorption, magnetism and luminescence on two polymers constructed from 1,3,5-benzenetribenzoate ligand

<div><p>Solvothermal reaction of 1,3,5-benzenetribenzoic acid (H<sub>3</sub>btb) with metal salts yielded two compounds with chemical formulas {(Me<sub>2</sub>NH<sub>2</sub>)[Zn(btb)(DMA)]·DMA}<sub>n</sub> (<b>1</b>) and [Mn<sub>3</sub>(btb)<sub>2</sub>(DMA)<sub>4</sub>·4DMA] (<b>2</b>) (DMA = N,N′-dimethylacetamide). <b>1</b> shows a 3-D fourfold interpenetrating (6,3) topological net, which has 1-D channels with counter anion and guest DMA molecules. <b>2</b> contains a 2-D bilayer structure based on a carboxylate-bridged Mn<sub>3</sub> cluster. <b>1</b> has no significant adsorption for H<sub>2</sub> and N<sub>2</sub> gas upon desolvation by long-time thermal activation, indicating that access to the void space is blocked by the immovable anions and interpenetrated feature. In addition, the 3-D luminescence for <b>1</b> and magnetism for <b>2</b> were also explored.</p></div>
