| Abstract: 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. |
