Hydrothermal reactions of lead(II) carbonate with 1,3,5- benzenetricarboxylic acid (H3BTC) and butylimino- bis(methylenephosphonic acid) (CH3CH2CH2CH 2N(CH2PO3H2)2, H 4L1) or lead(II) acetate with H3BTC and isobutylimino-bis(methylenephosphonic acid) (Me2CHCH 2N(CH2PO3H2)2, H 4L2) afforded two novel lead(II) carboxylate phosphonate hybrids, namely, Pb5(HL1)2(L 1)·H3BTC 1 and Pb4(BTC)(L 2)(CH3CO2)(H2O)2· 1.5H2O 2. The structure of compound 1 contains a 〈002〉 lead(II) diphosphonate hybrid layer formed by Pb(II) ions interconnected by HL1 and L1 anions. In compound 2, the interconnection of Pb(II) ions through bridging diphosphonate L2 anions lead to the formation of the 〈200〉 lead(II) diphosphonate 2D layer. In compound 1, the 1,3,5-benzenetricarboxylic acid acts as an intercalated species whereas in compound 2, the 1,3,5-benzenetricarboxylate anion adopts a hexadentate chelating and bridging coordination mode.

A series of zirconium alkyl-N,N-dimethylenephosphonate silver-carrying (Ag-ZRDP) were successfully prepared and their potential applications as synergistic antibacterial materials were investigated. Silver nanoparticles (Ag NPs), of 30 nm in diameter, were tightly anchored onto the zirconium alkyl-N,N-dimethylenephosphonate (ZRDP), increasing the antibacterial activity of the Ag NPs due to a decrease in the extent of nanoparticle aggregation. Due to the synergistic antibacterial effect of the Ag NPs and ZRDP, the Ag-ZRDP showed a better antibacterial activity than Ag NPs and ZRDP with a minimal inhibition concentration (MIC) of 0.25 and 0.25 μg mL-1 against Escherichia coli and Staphylococcus aureus, respectively. Additionally, the Ag-ZRDP did not show obvious cytotoxicity against mammalian cells (A549 cells), even at a concentration of 256 μg mL-1. Collectively, these properties make the newly synthesized Ag-ZRDP potentially superior as disinfectants and antiseptics for various biomedical and biotechnological applications.
