A photoluminescent metal–organic framework with threefold interpenetrated diamond topological net

A new 3D metal–organic framework, [Zn3(IN)6]⋅DMF⋅H2O (1, H-IN = isonicotinic acid), has been solvothermally synthesized and structurally characterized by single crystal X-ray diffraction. Structural analysis shows that compound 1 possesses a three-dimensional framework with 4-connected threefold interpenetrated diamond (dia) topological network where the Zn(II) centers are all 4-coordinated. Moreover, the photoluminescent property of this compound is investigated in the solid state at room temperature.
