Abstract


A new d10‑based Zn(II) coordination polymer (CP), formulated as [Zn(SO4)3(DMF)3]n (1), has been synthesized and structurally characterized. The single crystal X-ray diffraction results indicates that CP1 forms 1D inorganic –[Zn–SO4–Zn]n– chain along the ac plane. The thermal stability, UV/Vis diffuse-reflection spectrum and photocatalytic behavior of 1against organic dyes have been investigated. The photocatalysis results indicate that1displays better photocatalytic activities against RhBin comparison toMV. The probable mechanism associated with the photocatalysis of 1 against organic dyes has been addressed using density of states (DOS) calculations.
