Abstract

Abstract: A coordination polymer, [Pb2 (OH)(tzia)]·2H2 O (1 ), has been prepared by solvothermal reaction of 5-(1H-tetrazol-5-yl)isophthalic acid (H3 tzia) and Pb(NO3 )2 . The polymer1 is based on an unprecedented centrosymmetric tetranuclear [Pb4 (OH)2 (COO)4 (ttaz)2 ] cluster linked by a multidentate tzia ligand, affording a 2-D 3, 6-connectedkgd layer. The adjacent layers are further jointed by Pb⋯O interactions to form a 3-D supramolecular framework with a rare (3, 8)-connectedtfz-d; UO 3 topology. Photoluminescent properties of H3 tzia, 1, and1 -desolvated have been further investigated, and it was interesting to find that1 -desolvated due to the removal of lattice water molecules reveals stronger photoluminescence than1 .
