A first 1,2,4-triazole PbII Complex: Thermal, spectroscopic and structural studies, [Pb2(trz)2(CH3COO)(NO2)]n

A 3D PbII coordination polymer containing 1,2,4-triazole (trz) and two different anions, [Pb2(trz)2(CH3COO)(NO2)]n has been synthesized and characterized by elemental analysis, IR-, 1H NMR-, 13C NMR spectroscopy and studied by thermal as well as X-ray crystallography. The single-crystal X-ray data shows two types of Pb2+-ions with coordination numbers of seven, Pb(1) and Pb(2) with hemidirected and holodirected geometries, respectively.
