Two new lead(II)-organic frameworks Pb2(μ4-O)(bdc) ·DMF (1) and Pb(ndc)(DMF) (2) (H2bdc = 1,4- benzenedicarboxylate, H2ndc = 2,6-naphthalenedicarboxylate, DMF = N,N′-dimethylformamide) were prepared through solvothermal methods. Single-crystal X-ray diffraction analysis indicated that compounds 1 and 2 exhibit rod-based three-dimensional (3D) porous frameworks with 1D channels. The carboxylate groups in both compounds adopt different types of coordination modes, and the coordination geometries of lead(II) centers in compound 1 and 2 are hemidirected and holodirected, respectively. Gas sorption results showed that compound 1 has moderate uptakes for nitrogen and hydrogen gases, owing to the existence of micropores in structures. © 2013 Elsevier Inc. All rights reserved.
