H2L4 = C17H13NO2) and β-diketones (acetylacetone/dibenzoylmethane) in a 1:1:2 stoichiometry using dry benzene and ethanol as solvents. All these newly synthesized solid derivatives were fairly soluble in common organic solvents. They were characterized by elemental analyses, FTIR and NMR (1H and 13C) spectral studies. Single crystal XRD data of complexes 1, 2, 3 and 5 indicated the hepta-coordination and monomeric

Oxo-rhenium(V) mixed-ligand complexes with bidentate functionalized phosphines and tridentate Schiff base ligands
bidentate functionalized phosphines and tridentate Schiffbase (SB) ligands have been synthesized via ligand-exchange reactions starting from labile Re(V) precursors. A convenient route of synthesis is provided by the isolation of intermediate species such as [Re(O)(Ln)Cl3]− (1–3), (Ln=bidentate phosphino-phenolato or phosphino-carboxylato ligands). Subsequent addition of the relevant SB affords neutral

Towards a global greener process: from solvent-less synthesis of molybdenum(<scp>vi</scp>) ONO Schiff base complexes to catalyzed olefin epoxidation under organic-solvent-free conditions
characterised by means of IR spectroscopy, thermal analyses and also by powder and five molybdenum complexes by single crystal X-ray diffraction. The crystalstructure analysis of mononuclear complexes reveal distorted octahedral Mo(VI) coordination by ONO donor atoms from a dianionic tridentate Schiffbaseligand, two oxido oxygen atoms from the MoO22+ moiety and an oxygen atom from the MeOH molecule trans
Syntheses and characterizations of square planar nickel(II) complexes with pendant ligands: Examples of bi-dentate bonding modes of potentially tri- and tetra-dentate Schiff bases
tridentate ONO-donor ligand HL1 and potential tetradentate ONOO-donor ligand HL2 coordinate the nickel(II) only through the amine N and phenolic O to form complexes 1 and 2 respectively, i.e. the ligands act as pendantligands. On the other hand, the potential tetradentate ONOO-donor Schiff base H2L3 coordinates the nickel(II) only through the amine N atom and two phenolic O atoms to form complex 3, i.e. it
