A new concept for generation of chelating ligand libraries for homogeneous metal complex catalysis based on self-assembly is presented. Thus, self-assembly of structurally simple monodentate ligands in order to give structurally more complex bidentate ligands is achieved employing hydrogen bonding. Based on this concept and on the 2-pyridone/hydroxypyridine tautomeric system, a new rhodium cata...

The scanning atom probe (SAP) developed in the authors’ laboratory has a microelectrode that localizes electric field around sample apex. can be applied for measurement of non-bulk, non-solid materials. metal chelate compounds supported on carbon fiber (CF) were successfully analyzed by using polyethylene glycol as matrix and CF support emitter. bonds between Fe2+ ion bidentate ligands 1,10-phe...

Using a scalar relativistic all-electron density functional method, we studied uranium(VI) complexation with benzoic acid and its derivatives in aqueous solution as models of uranyl humates. We explored monodentate, bidentate, and chelate coordination of various isomers of methyl and hydroxyl substituted benzoic acid ligands. Monodentate complexes were determined to be energetically preferred a...

The title compound, [Fe(C 2 N 3 ) (C 8 H 7 5 ]·2H O, has been synthesized solvothermally and characterized by single-crystal X-ray diffraction. octahedral iron coordination polyhedron contains two di(pyrimidin-2-yl)amine ligands coordinated in a bidentate fashion, monodentate dicyanimido ligands, each via terminal atom, with the latter cis orientation. ligand configuration about atom is chiral,...
