Assembling nanosized ring-shaped synthons to an anionic layer structure based on the synergetically induced functional complementarity of their surface-sites: Na21[MoVI126MoV28O462H14(H2O)54(H2PO2)7]·xH2O (x ≈ 300)

Abstract

The reaction of an aqueous solution of sodium molybdate with hypophosphorous (phosphinic) acid acting both as reducing agent and ligand at low pH values (≈1) results in the formation of nanosized ring-shaped cluster units which assemble to form layers of the compound Na21[MoVI126- MoV28O462H14(H2O)54(H2PO2)7]·xH2O 1 (x ≈ 300); the assemblage is based on the synergetically induced functional complementarity of amphiphilic O[double bond, length half m-dash]MoL (L = H2O, H2PO2–) groups and corresponds to the replacement of H2O ligands of rings by related terminal Mo[double bond, length half m-dash]O groups of other rings (and vice versa) the nucleophilicity of which is induced by coordinated H2PO2– ligands.
