mino)phenol (HL1) and L2 is the deprotonated form of 4-tert-butyl-2-(2-hydroxy-3-methoxybenzylideneamino)phenol (HL2), have been synthesized. Structures of the complexes were characterized by elemental analysis, IR and UV-Vis spectroscopy, and single crystal X-ray diffraction. The Ni ions in the complexes are in octahedral coordination, and the Zn ions are in distorted square pyramidal coordination
We present the syntheses, crystalstructures, magnetic properties and theoreticalcalculations performed on two dinuclear dysprosium complexes with formulas Dy2(L1)2(L2)2(CH3CH2OH)(CH3OH) (1) and Dy2(L1)2(L3)2(CH3OH)2·1.5CH3OH (2). Single-crystal X-ray structural data analyses showed that both complexes contain two nonequivalent dysprosium ions bridged by two phenolate oxygen atoms. In both complexes
