文摘

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鈰疧 hydrogen bonds. Cu²⁺ ions are strongly antiferromagnetically coupled with singlet-triplet energy gap of about 2m>Jm> = 鈭?50 cm^鈭?, giving rise to interesting EPR properties.
