• A new binuclear copper(II) complex with tris(1-propan-2-onyl oxime)amine acting as a ligand was synthesized.
• Studies of magnetic properties show strong antiferromagnetic coupling.
• Well-resolved EPR spectra were obtained for powdered samples.
Perchlorate salt of a new binuclear [Cu2] cationic complex (1) with tris(1-propan-2-onyl oxime)amine acting as a ligand is introduced. In each complex cation two Cu2+ cations are linked by oxime groups from two ligands, whereas two remaining oxime groups per ligand remain non-deprotonated and participate in bifurcated O–H⋯O hydrogen bonds. Cu2+ ions are strongly antiferromagnetically coupled with singlet–triplet energy gap of about 2J = −750 cm−1, giving rise to interesting EPR properties.
Structure and properties are described for a new binuclear Cu(II) complex of a tripodal oxime ligand, exhibiting a strong antiferromagnetic coupling of the Cu(II) ions and interesting EPR properties.Figure optionsDownload as PowerPoint slide
