通过水热法合成得到1个以1,8-萘二酸(1,8-nap)为配体的Ba(11)配合物[Ba(μ5-1,8-nap)]n (1). X射线单晶衍射测定结果表明:配合物属于单斜晶系,空间群P2_1/c.配合物最小不对称单元由1个九配位的钡原子和1个1,8-萘二酸配体构成.每个1,8-萘二酸配体连接五个钡原子,每个钡原子连接五个1,8-萘二酸配体,在(100)平面上形成二维双层结构.此外,对配合物的固态荧光性质做了测定,结果显示其在紫光区有荧光发射.%The title complex, [Ba(/as-1,8-nap)],, (1), was the first barium complex based on naphthalene-1,8-dicarboxylate (1,8-nap) ligand, has been synthesized by hydrothermal method. It belongs to monoclinic system with space group P2,lc, a=1.551 80(7) run, b=0.830 32(4) nn, c=0.816 72(4) nm, β=93.973(3)°, V=1.049 81(9)nm3, D,=2.224 g·cm~(-3), Z=4, F(000)=664, the final R1=0.0479, wR2=0.124 2. The crystal structure of complex 1consists of a 9-coordinated Ba(Ⅱ) atom and a 1,8-nap ligand. Each 1,8-nap ligand links five Ba(Ⅱ) atoms and each Ball) atom attaches to five 1,8-nap ligands to form a 2D bilayer framework along the (100) plane. The luminescence of complex 1 has also been investigated, and results reveals that it displays luminescent property in the voilet region.
