Indirectly In-Situ Hydrothermal Preparation of a Novel Ag Tetrazole Coordination Polymer

在水热条件下,硝酸(3-氰基吡啶)银以及叠氮化纳反应,成功地组装了一个二维层状银四唑配位聚合物[mono(5-(3-pyridyl)tetrazolato)Ag](1),并对其进行了表征。晶体结构分析表明,化合物1结晶在三斜晶系,其空间群分别为P1(a=0.62608(10)nm,b=0.78498(13)nm,c=0.80584(12)nm,α=75.171(4)°,β=76.653(3)°,γ=68.332(3)°,V=0.35167(10)nm3,Z=2),银的配位环境为四配位并形成略为变形的四面体构型。室温下,化合物1显示强的蓝色荧光(495nm和521nm)。

The.-reaction of Ag(3-cyanopyridine)NO3 with NaN3 in presence of water and ethanol affords an unprecedented 2D layered tetrazole coordination polymer, [mono(5-(3-pyridyl) tetrazolato)Ag], [(3-PTZ)Ag] (1), which is characterized by single crystal X-ray determination, IR and fluorescent spectrum. The local coordination geometry around the Ag ion can be best described as a slightly distorted tetrahedron. The fluorescent emission spectrum of 1 at the solid-state at room temperature shows that maximal emission peak occurs in 495 and 521 nm, respectively. Crystal data for 1, C6H4AgN5, trielinic, P1, a=0.62608(10) nm, b=0.78498(13) nm, c=0.805 84(12) nm, alpha=75.171(4)degrees, beta=76.653(3)degrees, gamma=68.332(3)degrees, V=0.351 67(10) mn(3)degrees, Z=2.
