Abstract
A novel Zn(II)-cluster-based coordination polymer-namely, {[Zn8(μ4-O)2(1,4-ndc)6(DMF)3]⋅DMF}n (1) was synthesized using Zn(NO3)2 with 1,4-naphthalenedicarboxylic acid (1,4-H2ndc) under solvothermal conditions using CH3OH/H2O/DMF (6:1:1) as solvents and characterized by single crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, and luminescent measurements. The complex 1 features a 3D structure based on the octanuclear metal cluster of [Zn8(μ4-O)2(OOCR)12(DMF)3] as secondary building unit, which possesses a (412·63) network topology considering the octanuclear cluster as 6-connected nodes. Thermal property and photoluminescence investigations revealed that the complex 1 displays a high thermal stability, and a strong emission spectrum peak at 403nm at room temperature, and the complex 1 may be a technically viable option for the luminescence materials.
