Plumbum(Ii) and Zinc(Ii) Complexes With 5-Chlorosalicylic Acid: Structure and Propertie

Two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (h2l5), and 1,10-phenanthroline（phen）and 1,3-di(4-pyridyl)propane (bpp) as secondary ligands are reported, these two are formulated as {[pb(hl5)2(phen)(h2o)]·h2o}n (1), and [zn2(hl5)4(bpp)2]n (2), and are characterized by single-crystal x-ray diffraction. compoud 1 crystallizes in the triclinic p-1 space group while compoud 2 in the monoclinic system with space group c2/c. in compund 1, the carboxylate group of the coordinated hl5- adopt к^2o,o' coordination fashion to connect one pb(ii) ion but all the carboxylate groups adopt the different μ1-η^1: η^1 mode in the crystal of compoud 2 compared to 1. the solid-state photoluminescent properties at room temperature and thermal decomposition process of complexes were investigated.
