摘要
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(Ⅱ)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P21/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(μ5-1,8-nap)]n(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 P21/c,a=1.551 80(7) nm,b=0.830 32(4) nm,c=0.816 72(4) nm,β=93.973(3)°,V=1.049 81(9) nm3,Dc=2.224 g·cm-3,Z=4,F(000)=664,the final R1=0.047 9,wR2=0.124 2.The crystal structure of complex 1 consists 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 Ba(Ⅱ) 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.CCDC:778610.
