Five new 3D MOFs: {[Zn<sub>3</sub>(HL)<sub>2</sub>H<sub>2</sub>O]·4H<sub>2</sub>O}<sub>n</sub> (1), {[Ba<sub>2</sub>L<sub>5</sub>H<sub>2</sub>O]·2H<sub>2</sub>O}<sub>n</sub> (2), {[Ba<sub>4</sub>(L)<sub>2</sub>·5H<sub>2</sub>O]·2H<sub>2</sub>O}<sub>n</sub> (3), {[Cd<sub>3</sub>(HL)<sub>2</sub>·Cl<sub>2</sub>·2H<sub>2</sub>O]·2H<sub>2</sub>O}<sub>n</sub> (4) and {[Cu<sub>2</sub>(L)<sub>2</sub>·2H<sub>2</sub>O]·4H<sub>2</sub>O}<sub>n</sub> (5), were constructed based on 1-(3,5-dicarboxylatobenzyl)-3,5-pyrazole dicarboxylic acid. Structural analysis shows that 1-5 have 3D frameworks, among which 1(Zn) exhibits high luminescence sensing for Fe<sup>3+</sup> ions, excellent framework stability and reusability. The sensing mechanism of 1(Zn) is briefly discussed. In addition, 5(Cu) displays antiferromagnetic exchange phenomena.
