Extending the lanthanide–terephthalate system: Isolation of an unprecedented Tb(III)-based coordination polymer with high potential porosity and luminescence properties
Résumé
A novel coordination polymer with chemical formula {[Tb(bdc)1.5(H2O)](DMF)(H2O)}1 (1) has been synthesizedby reaction between 1,4-benzene-dicarboxylic acid (H2bdc) and di-cationic hexanuclear entity[Tb6O(OH)8(NO3)6(H2O)12]2+ in an ethylene glycol (EG)/N,N-dimethylformamide (DMF) mixture. Thiscompound has been obtained as single crystals by slow evaporation in air at room temperature. If thehexanuclear entity is destroyed during the reaction, the coordination polymer that is obtained is originaland presents promising potential micro-porosity and luminescent properties. It crystallizes in the monoclinicsystem, space group C12/c1 (No. 15) with the cell parameters a = 23.7540(1) Å, b = 10.5390(4) Å,c = 19.7580(3) Å, b = 125.8100(1) and Z = 8.
