Synthesis and structural characterization of two novel 2D coordination polymers [PbCl(atza)]n and [PbCl(a4-ptz)]n

Reactions of Katza (atza− = 5-aminotetrazole-1-acetato) or Ka4-ptz (a4-ptz− = 5-[N-acetato(4-pyridyl)]tetrazole) with PbCl2in aqueous solution, produced two new Pb(II) compounds, [PbCl(atza)]n (1) and [PbCl(a4-ptz)]n (2). Both compounds were structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. In 1 or 2, the Pb(II) centers are connected through the atza− or a4-ptz− bridging ligand to form a two-dimensional layered structure. The luminescence properties of 1 and 2 were investigated at room temperature in the solid state.
