TLDR
In this paper, N-Methylation of 2-pyridyphosphonic acids is shown to involve direct attack rather than a route through O-methylation followed by rearrangement.Abstract:

Three-Dimensional Lanthanide(III)–Copper(II) Compounds Based on an Unsymmetrical 2-Pyridylphosphonate Ligand: An Experimental and Theoretical Study
TL;DR: Based on an unsymmetrical 2-pyridylphosphonate ligand, two types of Ln(III)-Cu(II) compounds with three-dimensional structures were obtained under hydrothermal conditions, which showed that both the lanthanide contraction and the electron configuration of Cu( II) play important roles.

Magnetization relaxation in a three-dimensional ligated cobalt phosphonate containing ferrimagnetic chains.
TL;DR: A novel mixed ligated cobalt phosphonate is presented, in which the Co or Mn ions are antiferromagnetically coupled, thus resulting in spin canting structures with SCM behaviors.

Tetranuclear clusters containing a CrIII-doped MnIII4O2 core: syntheses, structures, and magnetic properties.
TL;DR: In this paper, the oxidation of MnII carboxylates by (NBu4)Cr2O7 in the presence of different phosphonic acids and chelating ligands results in six CrIII-doped tetranuclear manganese clusters formulated [Mn3CrO2(O2CCH3)4(O3PC5H4N)2(bpy)2]

Copper Phosphonates based on 2-Phosphonic-isonicotinate: Structures and Magnetic Properties
TL;DR: In this article, two copper phosphonates (CuO2O2 and CuO6) are linked by O(1W) octahedra through O(W) forming an inorganic chain.

Nature of the LnIII-COII magnetic interactions in compounds [Ln2Co3(C5H4NPO3)6]·4H2O with open-framework structures
TL;DR: In this article, the authors investigated the magnetic properties of Ln 2 Co 3 compounds and found that the Ln 3 -Co II interaction is weak antiferromagnetic and ferromagnetic for Ln 1 -Co 2 compounds.
