Synthesis and properties of tetra-μ-acetatodiruthenium(II,III) phenylphosphinate and phenylphosphonate complexes: X-ray crystal structures of [Ru2(μ-O2CCH3)4(HPhPO2)2]H and [Ru2(μ-O2CCH3)4(PhPO3H)2]H·H2O

Molecular Metal Phosphonates

“…These complexes possess the so-called Wells−Dawson type Fe 6 Ln 6 core, as shown in Figure 101. The inner part of the core contains six Fe III ions, while the outer part is occupied by six Gd III 232 In both of these compounds, the phosphinate/phosphonate ligands do not play any role in elaborating the nuclearity of the compound and only serve as terminal ligands (Figure 102a and b) (Figure 103). 233 There are no reports on molecular osmium phosphonate complexes.…”

Influence of Hydrogen Bonds in 1:1 Complexes of Phosphinic Acids with Substituted Pyridines on 1H and 31P NMR Chemical Shifts

“…For example, the geometric and spectroscopic parameters of acid monomers are not yet obtained experimentally. Acid–base complexes with phosphinic acids could be studied computationally, both in vacuum and in model solvents. , In general, the existent data suggest that the proton donor ability of phosphinic acids is significantly higher than that of carboxylic acids, which matches the higher acidity of phosphinic acids. , The interest in complexation properties of phosphinic and other phosphorus-containing acids is supported by their use as ligands for binding metal ions , or their hydroxides, also for the purposes of extraction. , POO moieties are used for a multitude of purposes as functional groups in polymers and surface interfaces. , Intermolecular hydrogen bonds formed by POOH groups in metal complexes of aryl-phosphinic acids determines the crystal packing of such complexes, which form single molecular magnets. − Phosphates could be used as proton conducting groups in membrane materials for fuel cell applications. − Further, various phosphates are abundant as both plant nutrients and agricultural pollutants.…”

Novel Layered Ruthenium Diphosphonate Containing a Mixed Valent Diruthenium Paddlewheel Core

“…The Ru 2 (hedp) 2 3core has a typical paddlewheel coordination motif, similar to that of diruthenium complexes of carboxylates and other oxyanions. 2,[13][14] To the best of our knowledge, no example of ruthenium phosphonates with extended structure has been reported previously except a few discrete species including a dinuclear compound 15 where the phosphonate group serves as a terminal ligand.…”
