Novel double-chained or double-layered metal diphosphonates: synergic coordination effect of two closely linked phosphonate moieties promoted by large metal ionic radius

Abstract

Hydrothermal reactions of PbII or BaII ion with N,N-dimethylaminomethane-1,1-diphosphonic acid (H4L) afforded a double-chained lead(II) diphosphonate and a double-layered barium(II) diphosphonate, namely, [Pb(H2L)] (1) and [Ba2(H2L)2] (2). The two closely linked phosphonate moieties in the diphosphonate ligand exhibit a highly synergic coordination effect, which is mainly promoted by the large ionic radius of the PbII or BaII ion. More interestingly, the unusual double-layer structure in 2 contains cubane-like Ba8 cages and each cage is face-shared with four adjacent ones.
