A novel 3D metal-organic framework with silver iodide anion cluster [Ag14I16](2-) as node : Synthesis, structure, and fluorescence property

• A novel 3D silver iodide metal-organic framework {[Ag14I16(HDABCO)(2)]center dot(DABCO)}(n) (DABCO = 1,4-diazabicyclo[2.2.2]octane) (1) has been synthesized solvothermally. In this compound, a [Ag14I16](2-) anion cluster was formed by twelve AgI4 tetrahedra and two AgI3 triangles by sharing their edges, in which its charge is compensated by two mono-protoned HDABCO(+). Each [Ag14I16](2-) cluster connects to six neighboring clusters by sharing corner I- ions between the AgI4 tetrahedra, resulting in a 3D framework. The compound 1 displays intense fluorescence emission with maximum at 400 nm and 465 nm upon 310 nm excitation at room temperature.
