Under hydrothermal conditions using cis-butenedioic acid (H2L) and corresponding lead(II) salts, a three-dimensional (3D) lead(II) complex {[Pb2(L)(μ2-Cl)(μ3-Cl)]}n (1) containing 3D Pb-X-Pb (X = O and Cl) linkage has been isolated. 1 also represents a truly 3D hybrid luminescent lead(II) framework with I3O0 type connectivity. Further analysis reveals that cis- and trans-conformations of butenedioic acid ligand greatly affect the lead(II) framework structure. Solid-state fluorescence spectrum of 1 exhibits the maximum emission peak at 379 nm. © 2009 Elsevier B.V. All rights reserved.

Under hydrothermal conditions, using 5-methyl-pyrazine-2-carboxylic acid (HL) and lead(II) bromide, a new 2D lead(II) framework [Pb(L)(μ2- Br)(H2O)]n (1) can be isolated, in which infinite Pb-O-Pb and Pb-Br-Pb helical chains can be observed. The crystal crystallizes in the monoclinic system, space group P2(1)/c, a = 7.5493(10), b = 6.6775(9), c = 19.335(3) Å, β = 92.884(2)°, and Z = 1. The X-ray analysis shows that strong O-H⋯N and weak O-H⋯Br hydrogen bonds further extending 1 into a 3D supramolecular packing architecture. Solid state luminescent spectrum of 1 also has been investigated indicating strong emission bands centered at 453 nm. Copyright © Taylor & Francis Group, LLC.
