An organometallic non-aqueous route to zinc phosphonates and to their intercalates has been studied. Various phosphonic acids react with dimethylzinc in THF media to afford the corresponding layered zinc phosphonates Zn(O

A MnIIphosphonate of the general formula [Mn(H2L)2(H2O)2(H2bibp)] adopts a layered motif with protonated H2bibp2+ cations embedded in the channels (H4L=thiophene‐2‐phosphonic acid; bibp=4,4′‐bis(1‐imidazolyl)biphenyl). The title compound exhibits excellent adsorptive removal of methylorange (MO) dye from aqueous solution. Its advantageous features include fast adsorption, high uptake capacity, selective
