摘要: Abstract 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 2 exhibit rod-based three-dimensional (3D) porous with 1D channels. The carboxylate groups in both adopt different types of coordination modes, the geometries lead(II) centers compound are hemidirected holodirected, respectively. Gas sorption results showed has moderate uptakes for nitrogen hydrogen gases, owing to existence micropores structures.
