A Three-Dimensional Porous and Magnetic Framework Constructed from {Cu4(μ4-Cl)}+7 Clusters and 4-(1H-Tetrazol-5yl)-benzoic Acid, (Me2NH2)[Cu4Cl(tba)4(H2O)4]•2DMF

The hydrothermal reaction of CuCl2 center dot 2H(2)O and 4-(1H tetrazol-5-yl)-benzoic acid (H(2)tba) in the presence of excess HCl yielded the three-dimensional material (Me2NH2)[Cu4Cl(tba)(4)(H2O)(4)]center dot 2DMF. The structure is constructed from {Cu-4(mu(4)-Cl)-(H2O)(4)}(7+) clusters linked through tba(2-) ligands into an open framework with 57% void volume. The microporosity and magnetic properties of the material were investigated.
