Study on 1D chain coordination polymer of cinnamaldehyde salicyl hydrazone cadmium complex

A one-dimensional (1D) chain coordination polymer [Cd2L4(DMF)(2)](n) (HL = C16H14N2O2) has been synthesized and characterized by physicochemical and spectroscopic methods, cyclic voltammetry and single crystal X-ray structure analysis. The complex crystallizes in the monoclinic system, and each Cd(II) of the complex is a six-coordinate with a distorted octahedral geometry. Cinnamaldehyde salicylhydrazone, C16H14N2O2 as bridging ligands, links the neighboring Cd(II) atoms in a head-to-tail mode. They construct an infinite zigzag chain along the c axis. Cyclic voltammetry shows that the complex has a weak reductive centered at -0.328 V and an oxidative peak at 0.410 V. Fluorescence spectra indicate that the band of complex at 285 nm has a 30 nm red-shift compared with HL.
