  • Keggin-Type H5PMo10V2O40Intercalated MgAl-LDH: Structural Integrity and Bifunctional Electrocatalytic Activity
    Pushparaj Loganathan, Kalathiparambil Rajendra Pai Sunajadevi, Devaraj Muthukumar
    Inorganic Chemistry, 2026
    The development of earth-abundant electrocatalysts is central to sustainable water electrolysis, yet many systems are limited by poor electronic conductivity and inadequate durability. In particular, the high solubility of discrete polyoxometalates (POMs) clusters hinders their direct deployment as stable heterogeneous electrocatalysts. Here, a Keggin-type H5PMo10V2O40 POM is intercalated into MgAl layered double hydroxide (MgAl-LDH) by a formamide-assisted exfoliation-reassembly strategy to afford a POM@MgAl-LDH hybrid. Structural characterization confirms quantitative ion exchange of POM anions into the LDH galleries and an increase of the basal spacing to 9.2–10.5 Å. Density functional theory calculations indicate thermodynamically favorable intercalation (ΔE ≈ −2.3 eV per formula unit) and predict an equilibrium interlayer distance that matches the experiment. The hybrid exhibits a BET surface area of 50.6 m2 g–1 and hierarchical porosity. In 1.0 M KOH, POM@MgAl-LDH functions as a bifunctional electrocatalyst, affording hydrogen and oxygen evolution overpotentials of 215 and 411 mV at 10 mA cm–2, respectively, with ∼97% current retention over 12 h of electrolysis. These results suggest that spatial confinement of redox-active POM clusters within an earth-abundant MgAl-LDH host reduces POM loss into solution and improves the electrocatalytic response of LDH framework, offering a practical route to nonprecious-metal bifunctional electrocatalysts for alkaline water splitting.

  • Multisite Coordination Ligands on Cyclotriphosphazene Core for the Assembly of Metal Clusters and Porous Coordination Polymers
    Velusamy Jeevananthan, Senthil A. Gurusamy Thangavelu, Pushparaj Loganathan, Swaminathan Shanmugan
    Chemistryselect, 2021
    In this review, we account the recent advancements on cyclotriphosphazene (N3P3Cl6) based multi‐site coordination ligands for the synthesis of multi‐metallic architectures. In case of N3P3Cl6, Phosphorous centres with two chlorides use to be bonded with nitrogen [−P(Cl2)=N−]3 at alternative positions in six membered ring to provide a robust planar structure to anchor the ligand arms with wide flexibility. Cyclic P−N robust motif is renowned as the potential support for the design of multi‐site ligands originating from phosphorus centres by viable substitution of variable number of ligand units (1 to 6) consist of one or more coordination site(s) via geminal and/or non‐geminal modes. Despite these phosphorus centres are promising to support in ligand structure, occasionally involve in coordination with transition metals as well. Three of alternative nitrogen atoms in this heterocyclic core are supposed to function as Lewis base centres while the electron releasing substituents occurred to tether on phosphorus centres, also when the resultant ring size favours adequate interaction towards the transition metal ions with respect to skeletal flexibility. The ligand modes vary with respect to numbers and orientation of coordination sites, which is imperative to enrich the ligation ability. Moreover, several examples of cyclotriphosphazene core ligands consist of the spacer oxygen atom while tethering with exocyclic ligand units to incorporate more flexibility. In accordance with coordination sites on ligand framework and choice of metal, the skeletal ring nitrogen atom(s) of the cyclotriphosphazene can be involved in coordination with metal ions. Indeed, the coordination of ligands is reported to coordinate with main group, transition and lanthanide metal ions to form variety of metal clusters and porous coordination polymers. Subsequently, the geometry of homo or heterometallic complexes with respect to versatile coordination modes of metallic complexes tends to afford inherent chemical properties for specific application. In terms of exocyclic ligands, the heterocyclic units such as pyridyloxy‐, pyrazolyl‐, pyridylalkylamino‐, bipyridyl‐, 1,10‐phenanthroline, porphyrinato, hydrazide, hydrazone, Schiff's base and spirocyclic amine units attached to cyclotriphosphazene were exploited to form series of metal complexes. Similarly, the variety of metal clusters, polymeric network (1D to 3D) and porous coordination polymers have been reported on basis of cyclic core molecule substituted with ligand units, pyridyloxy‐, multi‐carboxylic, aromatic amines substituted pyridyloxy‐ and imidazole moiety involved to form variety of products.
  • Synthesis and characterization of polymeric and monomeric zinc phosphinates
    Anusree Sukumaran, Buvanesh Shanmugam, Velusamy Jeevananthan, Pushparaj Loganathan
    Materials Today Proceedings, 2020
    The synthesis and characterization of polymeric and monomeric Zinc phosphinates are reported. Bis(hydroxymethyl)phosphinic acid is used as a ligand for the synthesis of both polymeric and monomeric phosphinates. A polymeric zinc phosphinate is synthesized by the reaction of bis(hydroxymethyl)phosphinic acid with zinc acetate dihydrate at room temperature. Each phosphinate ligand coordinates with two different zinc centers to generate polymeric zinc phosphinate. The above reaction is carried out with the addition of 1,10-phenanthroline to form monomeric zinc phosphinate compound. When the N-donor chelating ligand (1,10-phenanthroline) is introduced, the construction of polymeric zinc phosphinate is blocked by 1,10-phenanthroline which facilitates the formation of discrete monomeric zinc phosphinate. The synthesized zinc phosphinate compounds are characterized by FT-IR, 1H, 13C and 31P NMR, and also noticed thermal stability by thermogravimetric analysis (TGA). Both the polymeric and monomeric zinc phosphinate compounds are subjected for calcinations at 800 °C to produce zinc metaphosphate materials. Finally the crystalline phase of zinc metaphosphate materials is characterized by powder x-ray diffraction technique (PXRD).
