LiF-assisted crystallization of zinc 4-carboxyphenylphosphonates with pillared layered structures

Abstract: Two novel zinc phosphonates, namely Zn 2 Li 2 (OOCC 6 H 4 PO 3 ) 2 (1) and Zn 2 (OOCC 6 H 4 PO 3 )F (2) were hydrothermally synthesized by reacting zinc sulfate with 4-carboxyphenylphosphonic acid in the presence of additional LiF. Both display pillared layered structures, but with different layer topologies. In compound 1, {ZnO 4 } and {LiO 4 } tetrahedra are connected by {CPO 3 } tetrahedra via cornersharing, forming an inorganic net-like layer containing 3-membered rings. In compound 2, the fluoride anion s… Show more

“…Many other metallic precursors could also be utilized as the central ions to coordinate with phosphonic acids to obtain layered structures. 55,56 However, it is noteworthy that layered phosphonate hybrids often show up in the form of dense motifs. The pillars are too crowded to leave sufficient free space in the interlayer region, and thus poor or no porosity is expected.…”

“…To date, diverse bi-functional organophosphonic acid ligands containing various functional auxiliary groups (crown ether, amine, hydroxyl, and/or carboxylate, etc) have been used to control the formation and properties of CP [2633]. For example, recently a bifunctional aromatic organophosphonic acid ligand that contains a triazole moiety, 4-(1, 2, 4-triazol-4-yl)phenylphosphonic acid (H 2 ptz), has been synthesized and was used to stabilize three two-dimensional (2D) CPs containing Ni(II), Co(II), or Mn(II) metal ions [34, 35].…”

“…In some cases the other functional group is engaged in bonding to the metal ions, contributing to connectivity and structure. 1,2,4,5,[18][19][20] In others, these groups remain uncoordinated and potentially available for chemical reactivity in the final materials. However, a variety of structures can be obtained for even one combination of metal ion and ligand by using different solvents and varying the reaction temperature and pH.…”
