The ligands were designed to model aminated intermediate forms of the topaquinone (TPQ) cofactor in the enzymic cycle of Cu-dependent amine oxidases. The ligands, L, are coordinated to the metal centers through imine-N and phenolate-O donor atoms to form five-membered chelate rings, in contrast to the six-membered chelate rings of salen-type Schiff base ligands. (Bim(OH)O)Cu(PPh3)2·0.5MeOH was structurally analyzed and shown to exhibit intramol. aryl-aryl interactions between the ligands and intermol. H bonds involving the free phenolic hydroxyl substituent, the coordinated phenolate O atom and the MeOH solvate mol.
