Two 3D porous cadmium tetrazolate frameworks with hexagonal tunnels.
Two novel high-symmetry 3D porous frameworks, [Cd5(tetrazolate)9(OH)(H2O)]n.5nH2O (1) and [Cd5(5-aminotetrazolate)9(NO3)]n.3nH2O (2), have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction analysis. The structures of 1 and 2 are characteristic of hexagonal tunnels through the trigonal-prismatic and hexagonal tubelike building units and exhibit their high stabilities of porous frameworks against the removal of the guest molecules.
