A Novel 3D Silver-triazolate Coordination Polymer with 6.10~2 Topology:Synthesis,Crystal Structure and Phosphorescence

【摘要】 A novel three-dimensional (3D) silver(I) coordination polymer, namely [Ag2(dmtrz)2]n (1) (Hdmtrz=3,5-dimethyl-1H,1,2,4-triazole), was synthesized through diffusion method. 1 was characterized by elemental analysis, FT-IR spectroscopy, thermogravimetric analysis (TGA) and single-crystal X-ray diffraction. 1 crystallizes in the orthorhombic system, space group Iba2 with a=12.5026(10), b=7.6026(6), c=18.8981(17), V=1796.3(3)3, Z=6, Mr=407.98, Dc=2.263 g·cm-3, μ=3.252 mm-1, F(000)=1176, the final R=0.0304 and wR=0.0634 for 1310 observed reflections (I > 2σ(I)). In the structure of 1, silver(I) centers are triconnected to dmtrz ligands, forming the (3,3)-connected 3D coordination polymer with a 6.102 topology. The luminescence property of 1 was also studied in solid state at room temperature.更多还原
