摘　　要：The crystal structure of the title compound, Cl2·4H2O, (Im=imidazole) was determined by X-ray analysis. The crystal structure consists of Fe(Im)62+ cation, two Cl- anions and four non-coordinated water molecules. It crystallizes in the triclinic system, space group P1, with lattice parameters a=0.879 7(2) nm, b=0.906 8(2) nm, c=1.058 1(2) nm, α=75.35(3)°, β=83.20(3)°, γ=61.85(3)°, and Z=1; The Fe(Ⅱ) ion assumes centrosymmetric octahedron geometry with the FeN6 core. Six imidazole molecules are coordinated to each iron(Ⅱ) ion through its tertiary nitrogen atom. The bond distances of Fe-N are in range of 0.212 8(1) nm to 0.220 4(1) nm. In the solid state, 2+, H2O molecules and chlorine anions form three dimensional hydrogen bonds network which stabilized the crystal structure. Elemental analysis and electronic spectrum are in agreement with the structural data. The thermal gravity (TG) data indicate that thermal decomposition of the title compound takes place in five steps. In these cases, the residue may be Fe. From the cyclic voltammogram measurement in EtOH/H2O, we know that electrode reaction was a quasi-reversible process. CCDC: 215335.
