A complex [Cd(NCS)2(Vim)4] (where Vim=1-vinylimidazole) was synthesized and it's crystal structure was determined by X-ray diffraction technique. The compound crystallizes in the Monoclinic space group P21/c with the parameters: a=0.858 50(17) nm, b=0.909 90(18) nm, c=1.782 3(4) nm, β=100.14(3)°, V=1.370 5(5) nm3, Z=2. In the structure, each Cd atom is coordinated by four 1-vinylimidazole ligands and a pair of monodentate isothiocyanic groups, affording a compressed octahedral CdN6 core. The NCS-anions are trans and four N atoms from the 1-vinylimidazole ligands define the equatorial plane. From the cyclic voltammogram measurement in H2O, we know that the electrode reaction was
