Substituted group directed assembly of energetic lead(ii) compounds based on structure-relevant ligands

Abstract

Reactions of two structure-relevant ligands, Hpytz [Hpytz = 5-(4-pyridyl)tetrazole] and its 2H-tetrazole-carboxylate substituted derivative Hpytza [Hpytza = 5-(4-pyridyl)tetrazole-2-acetic acid] with Pb(NO3)2 under the presence of potassium hydroxide, afforded a new mononuclear [Pb(pytz)2(H2O)4]ยท3H2O (1) and a two dimensional polymer [Pb(pytza)2]n (2) with (4,4) topology, respectively. The two compounds were characterized by elemental analysis, IR and single crystal X-ray diffraction. The luminescence properties of compounds 1 and 2 investigated at room temperature in the solid state show both intraligand emission and characteristic peak of Pb2+. Differential scanning calorimetry (DSC) and thermogravimetric-differential thermogravimetric (TG-DTG) analyses were applied to assess the thermal decomposition behavior of compounds 1 and 2. The DSC test indicates that compound 2 can be taken advantage of as a potentially explosive material.
