Synthesis and structural characterization of two novel 2D coordination polymers [PbCl(atza)]n and [PbCl(a4-ptz)]n
摘要:
Reactions of Katza (atza(-)=5-aminotetrazole-l-acetato) or Ka4-ptz (a4-ptz(-)=5-[N-acetato(4-pyridyl)ltetrazole) with PbCl2 in 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 I or 2, the Pb(II) centers are connected through the atzaor 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. (c) 2008 Elsevier B.V. All rights reserved.
