摘　　要：A new 2-naphthate（NA-）-based coordination complex,[Cu3（μ3-OH）4（NA）2]n（1）,was hydrothermally prepared and structurally and magnetically characterized.1 crystallizes in the monoclinic P21/c space group with a = 19.990（7）,b = 5.616（2）,c = 9.179（3） A,β = 96.536（6）°,V = 1023.8（7） A^3,Dc = 1.950 g/cm^3,Mr = 300.49,Z = 4,F（000） = 602,μ = 3.138 mm^-1,the final R = 0.0317 and w R = 0.0818 for 4944 observed reflections with I 〉 2σ（I）.Complex 1 exhibits an extended corner-sharing {Cu3（μ3-OH）}^5＋ triangle-based layered structure with the NA^-ligands located on both sides.The interplay of the typical anti-and ferromagnetic interactions mediated by μ3-OH^-and μ-syn,syn-carboxylate heterobridges leads to the overall intralayer ferromagnetic couplings of 1.A new 2-naphthate（NA-）-based coordination complex,[Cu3（μ3-OH）4（NA）2]n（1）,was hydrothermally prepared and structurally and magnetically characterized.1 crystallizes in the monoclinic P21/c space group with a = 19.990（7）,b = 5.616（2）,c = 9.179（3） A,β = 96.536（6）°,V = 1023.8（7） A^3,Dc = 1.950 g/cm^3,Mr = 300.49,Z = 4,F（000） = 602,μ = 3.138 mm^-1,the final R = 0.0317 and w R = 0.0818 for 4944 observed reflections with I 〉 2σ（I）.Complex 1 exhibits an extended corner-sharing {Cu3（μ3-OH）}^5＋ triangle-based layered structure with the NA^-ligands located on both sides.The interplay of the typical anti-and ferromagnetic interactions mediated by μ3-OH^-and μ-syn,syn-carboxylate heterobridges leads to the overall intralayer ferromagnetic couplings of 1.
