Novel hybrid porous 3D networks of lead(II) diphosphonate and triphosphonate containing 1,3,5-benzenetricarboxylate Academic Article uri icon


  • Hydrothermal reactions of lead(II) acetate with 1,3,5-benzenetricarboxylic acid (H3BTC) and a new aminodiphosphonic acid, [3-pyridyl-CH 2N(CH2PO3H2)2] (H 4L1), or a new aminotriphosphonic acid, [1-{(H 2O3PCH2)2NCH2CH 2-}-piperazine-4-CH2PO3H2] (H 6L2), afforded two novel porous carboxylate-phosphonate hybrids, [Pb4(BTC)(HBTC)-(HL1)]3H2O (1) and [Pb6(BTC)2(HBTC)(H2L2)] 4.5H2O (2). The structure of 1 is built from a 3D porous network of lead(II) tricarboxylate and 1D double chains of lead(II) aminodiphosphonate. The structure of 2 contains 002 lead(II) carboxylate-phosphonate hybrid layers, which are cross-linked by 1D double chains of lead(II) phosphonate through the organic groups of both types of ligands, resulting in the formation of a complex 3D porous network. The lattice water molecules in both compounds are located at the micropores of the structures. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
