The X-ray single-crystal structure analyses have been determined for two metal imidazole chlorides: [Fe(Im)6]Cl2(4H2O 1 and [CuCl(Im)4]Cl 2 (Im ( imidazole). The red crystal of compound 1 is of triclinic, space group Pī with Mr = 607.31 (C18H32Cl2FeN12O4), a = 8.797(2), b = 9.068(2), c = 10.581(2)A, α = 75.35(3), β = 83.20(3), γ = 61.85(3)o, V = 720.0(2)A3, Z = 1, Dc = 1.401 g/cm3, F(000) = 316, μ = 0.755 mm－1, R = 0.0353 and wR = 0.1227. The blue crystal of compound 2 belongs to monoclinic, space group P21/c with Mr = 406.77 (C12H16Cl2CuN8), a = 13.909(3), b = 8.8933(18), c = 15.086(7)A, β = 118.32(2), V = 1642.7(9)A3, Z = 4, Dc = 1.645 g/cm3, F(000) = 828, μ = 1.666 mm－1, R = 0.0609 and wR = 0.1726. In solid state, both 1 and 2 form three-dimensional hydrogen bond networks to stabilize the structures which were also characterized by TG and elemental analyses. The thermal gravity (TG) data indicate that the residues are Fe and Cu for 1 and 2, respectively.
