Synthesis, physico-chemical and spectral investigations of novel homo-bimetallic mixed-ligand complexes: 57Fe Mössbauer parameters of [Fe2(imda)2(H2O)3Cl]

Synthesis, Characterization, and Application of Silica-Supported Copper-Doped Phosphotungstic Acid in Claisen–Schmidt Condensation

“…However, the copper-doped catalyst (Cu− H 3 PW 12 O 40 ) exhibited two EPR bands at g = 2.232 and 2.041 which confirmed the anisotropic nature of Cu 2+ species present in the catalyst. 45,46 ICP−AES analysis showed the wt % of Cu to be 8.1% which corresponded to the loading amount of 1.26 mmol/g of catalyst.…”

Prevention of Peritoneal Adhesions by Ferric Ion-Cross-Linked Hydrogels of Hyaluronic Acid Modified with Iminodiacetic Acids

“…FeHA is considered to form irreversible tight cross-linking points through monodentate coordination of three HA molecules, , in which counterion exchange with other iron chelators, such as phosphate ions, would be difficult to occur. On the other hand, HA–IDA would preferentially coordinate to Fe 3+ through μ-oxo bridges which would enable reversible and faster counterion exchange with iron chelators (Figure S5). This difference in Fe 3+ chelation would cause faster degradation of FeHA–IDA than FeHA in phosphate-containing media, including PBS and DMEM as well as peritoneal fluid, which would result in faster clearance of degradation products that might induce the adverse effects.…”

Synthesis, spectral characterizations and biological studies of transition metal mixed ligand complexes: X-ray crystal structures of [Cu(oda)(Bipy)(H2O)]·4H2O and [VO(oda)(Bipy)]·2H2O

“…The observed anisotropy in the spectroscopic Lande parameter (g || > g \ > 2.0) indicates an axial distortion [38] around Cu 2+ ion. Table 1.…”
