Targeted syntheses of homo- and heterotrinuclear complexes involving MII–NiII–MII (M=Ni, Cu, and Pd) nonlinear core: Structure, spectroscopy, magnetic and redox studies

Synthesis and Characterization of Novel Organocobaloximes as Potential Catecholase and Antimicrobial Activity Agents

“…Based on the results reported in the literature the structural parameters of the oximato‐bridged copper(II) complexes reveal that exchange interactions ( J values) show no correlation either with the distances CuCu, Cu/N oxime , Cu/O oxime , and N oxime /O oxime , or with the nature of the basal skeleton Cu(NO) 2 Cu, i.e., the magnitude of exchange coupling is independent of the degree of deviation from planarity, or deviation of copper from the mean basal plane. These observations might suggest that the unusually large spin exchange interaction in these trinuclear complexes containing two copper(II) is not the result of any special geometrical features but is related to the electronic structure of the bridging glyoximato ions .…”

A new mononuclear Fe(iii) Mannich-base complex with selective histidine binding and catechol oxidase activity

“…1310 cm À1 due to the n(C-O/phenolate) stretching vibrations. 28,29 Corresponding signature vibrations for the b-diketonate moiety in 1 appears in the form of a twin band at ca. 1590 and 1560 cm À1 due to u(CQC) and u(CQO) stretching, respectively.…”

Synthesis, Characterization and Catecholase Activity of Cobalt (Ii) Complexes With Phenol Based N2o2 Chelating Ligand

“…Both the two complexes give characteristic bands of the coordinated ligand (H2L). Complex 1 shows a prominent band at 1255 due to ῡ C-O / phenolate present in the ligand11 . Another strong bands arise at 1653 cm -1 and at 1352 cm -1 due to the symmetric and asymmetric stretching modes of vibration of carboxylate…”
