Novel lead(II) carboxylate–arsonate hybrids
چکیده انگلیسی

Hydrothermal reactions of lead(II) acetate with phenylarsonic acid (H2L1) (or 4-hydroxy-3-nitrophenylarsonic acid, H3L2) and 5-sulfoisophthalic acid monosodium salt (NaH2SIP) (or 1,3,5-benzenetricarboxylic acid (H3BTC)) as the second metal linkers afforded three novel mixed-ligand lead(II) carboxylate–arsonates, namely, Pb5(SIP)2(L1)2(H2O) 1, Pb3(SIP)(L2)(H2O) 2 and Pb(H2L2)(H2BTC) 3. The structure of 1 features a complicated 3D network composed of 2D double layers of lead(II) sulfoisophthalate bridged by 1D chains of lead(II) arsonates along b-axis, forming large tunnels along b-axis which are occupied by phenyl rings of the arsonate ligands. In 2, the Pb(II) ions are bridged by {L2}3− anions into a 2D double layer whereas the interconnection of the Pb(II) ions via bridging and chelating SIP anions gave a 2D double layer. The cross-linkage of the above two building units leads to a complicated 3D network. In 3, the interconnection of the Pb(II) ions via bridging {H2L2}− and {H2BTC}− anions leads to a 1D double chain down a-axis. These 1D chains are further interconnected via hydrogen bonds among non-coordination carboxylate groups and arsonate oxygens into a 3D supramolecular architecture.

Three novel mixed-ligand lead(II) carboxylate–arsonates, namely, Pb5(SIP)2(L1)2(H2O) 1, Pb3(SIP)(L2)(H2O) 2 and Pb(H2L2)(H2BTC) 3 have been synthesized and structurally characterized. Compounds 1 and 2 feature complicated 3D network structures whereas compound 3 features 1D lead(II) carboxylate–arsonate chains that are further interlinked by strong hydrogen bonds into a 3D supramolecular assembly.Figure optionsDownload as PowerPoint slide
