摘　　要：在中温水热反应条件下 ,以CoCl2 ·6H2 O、2 ,6 萘二羧酸 (2 ,6 pda)和 4 ,4’ bpy为原料 ,合成了一种二维互穿配位聚合物 [Co3 (2 ,6 nda) 3 (4 ,4’ bpy) 1.5]n 晶体 ,对其进行了元素分析、红外光谱表征、TGA GTA分析和X射线单晶衍射测定。该配位聚合物属单斜晶系 ,C2 /m空间群 ,晶胞参数为a =1.72 85 (11)nm ,b =1.996 5 (13)nm ,c=1.3994 (9)nm ,α =90° ,β=95 .82 2 (11)°,γ =90° ,V =4 .80 4 (5 )nm3 ,Z =4 ,dc=1.4 5 7g/cm3 ,μ =1.0 89mm-1,F(0 0 0 ) =2 136 ,R1=0 .0 5 94 ,wR2 =0 .16 0 5。结果显示形成一个二维互穿的网络结构。A two-dimensional interpenetrating coordination polymer [Co_3(2,6-nda)_3(4,4'-bpy)_(1.5)]_n was synthesized by hydrothermal reaction of CoCl_2·6H_2O and 2,6-naphthalenedicarboxylic acid (2,6-nda) and 4,4'-bpy. The structure was characterized by elemental analysis and IR spectroscopy as well as TGA-GTA analysis and X-ray single crystal diffractometer. The analysis reveals the structure consists of [Co_3(2,6-nda)_3(4,4'-bpy)_(1.5)]_n. The crystal is in monoclinic crystal system and C2/m space group. Crystallographic data: a = 1.7285(11)nm, b = 1.9965(13)nm, c = 1.3994(9)nm, α = 90°, β = 95.822(11)°, γ = 90°, V = 4.804(5)nm^3, Z = 4, d_c = 1.457g/cm^3,μ= 1.089mm^(-1), F(000) = 2136, R1 = 0.0594, wR2= 0.1605. X-ray analysis reveals that a two-dimensional interpenetrating net is formed.
