Abstract
Methods were developed for synthesizing the 3-Carene derivative (1R)-1-|(1R,2R,5R)-2-benzyl-3-imino-6,6-dimethylbicyclo[3.1.0]hex-2-yl}-ethanol (HL) and stable copper(II) complexes [Cu2(H2O)L2(CH3COO)2] · H2O (IV), [Cu2L2Cl2] (V), and [Cu2L2Br2] (VI). According to X-ray diffraction data, IVand Vhave molecular binuclear structures with a planar Cu2O2cycle. The CuOCu angles are equal to 102.2°, 102.8° (IV) and 103.2°, 103.8° (V). The L–terpene ligand acts as a tridentate cyclic bridge. A strong antiferromagnetic exchange interaction between the unpaired electrons of the copper(II) ions was detected in compounds IV–VIusing the static magnetic susceptibility method. The –2Jparameter for IV, V, and VIis equal to 660, 1000, and 1060 cm–1, respectively.
