3D purely inorganic lead-azide coordination polymer constructed by exclusive end-to-end azido binding

One pot synthesis of a purely inorganic framework of azido-lead(II) complex with molecular formula [Pb3(N3)6]n has been made by using 5-aminotetrazole (5-ATZ) ligand as starting material. X-ray single crystal structure determination revealed the presence of two types of Pb-centers (Pb1 and Pb2). One-dimensional propagation of Pb1 centers with azide segment gives an infinite zig-zag 1D chain along c-axis. 2D sheet is formed along bc- and ac-plane with the 1D chain. It is interesting to identify another infinite 1D chain along a-axis by connecting Pb2 centers via azide linkage. The compound displays an overall 3D structure. All the connectivity of azide in complex 1 show exclusive end-to-end (i.e., μ-1,3) binding.
