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

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, triclinic, P1, a=0.626 08(10) nm, b=0.784 98(13) nm, c=0.805 84(12) nm, α=75.171(4)°, β=76.653(3)°, γ=68.332(3)°, V=0.351 67(10) nm3, Z=2. CCDC: 267340.
