Abstract: A novel copper(Ⅱ)-sodium(I) mixed-metal coordination polymer [(CuL)2(CH3OO)Na(H2O)4]2 (abbreviated as 1)has been synthesized and characterized by elemental analysis and single-crystal X-ray diffraction, where H2L = 2-(2-hydroxyphenyl)-Δ 2-thiazoline-4-carboxylic acid. Crystal structure analysis reveals that 1 has an impendent symmetry unit consisted by two slightly different half of the Cu4Na2 six-nuclear molecular rings. Furthermore, the Cu4Na2 rings connect further with each other to form a two-dimensional network containing larger Cu8Na4 rings. Crystal data: triclinic, space group Pī with a = 1.0777(4) nm, b = 1.5221(6) nm, c = 1.6994(6) nm, α = 84.58(1) °, β = 76.31(1) °, γ = 89.97(1)°, V = 2.696 (2) nm3, Z = 2, Mr = 1447.26, dc = 1.783 g·cm-3, T = 293(2) K, μ=1.816 mm-1, F(000) = 1472, R1 = 0.0794, wR2 = 0.1819 [I>2σ(I)].
