(Elsevier Science Sa, Lausanne, 2005)
Novel N-N-N-O-type of tetradentate ligands H(3)obap (H(3)obap = oxamido-N-aminopropyl-N'-benzoic acid) and H(3)maeb (H(3)maeb = malamido-N-aminoethyl-N'-benzoic acid) and the corresponding square-planar copper(H) complexes ...
Very strong metal ligand aromatic cation-pi interactions in transition metal complexes: intermolecular interaction in tetraphenylborate salts
(Elsevier Science Sa, Lausanne, 2004)
Strong intermolecular interactions between ligands in cationic metal complexes and aromatic rings of tetraphenylborate anion, so-called metal ligand aromatic cation-pi (MLACpi) interactions, were found by screening Cambridge ...
Water soluble Eu(III) complexes of macrocyclic triamide ligands: Structure, stability, luminescence and redox properties
(Inorganica Chimica Acta, 2019)
Two macrocyclic triamide octadentate chelator scaffolds L1 and L2 were synthesized, characterized by several spectroscopic techniques, and their pKa values were determined by potentiometric titration. Using these ligands, ...
The Fe(III) complexes with a doubly deprotonated polydentate acylhydrazone: crystal structure of the first diamagnetic mu-oxo-diiron(III) complex
(Elsevier Science Sa, Lausanne, 2001)
The synthesis of two Fe(III) complexes with a doubly deprotonated polydentate of the acylhydrazone class is described. The first complex was obtained by hydrolyzing the previously synthesized high-spin pentagonal-bipyramidal ...
