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

Solvothermal reaction of 1,3,5-benzenetribenzoic acid (H₃btb) with metal salts yielded two compounds with chemical formulas {(Me₂NH₂)[Zn(btb)(DMA)]·DMA}_n (1) and [Mn₃(btb)₂(DMA)₄·4DMA] (2) (DMA = N,N′-dimethylacetamide). 1 shows a 3-D fourfold interpenetrating (6,3) topological net, which has 1-D channels with counter anion and guest DMA molecules. 2 contains a 2-D bilayer structure based on a carboxylate-bridged Mn₃ cluster. 1 has no significant adsorption for H₂ and N₂ 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 1 and magnetism for 2 were also explored.
