چکیده انگلیسی
Synthesis, spectroscopic and magnetic properties, and X-ray crystal structures of two copper(II) polymers Cu(2-qic)Br (2-qic = quinoline-2-carboxylate) (1) and Cu(2-pic)Br (2-pic = pyridine-2-carboxylate) (2) are described. Both complexes are polynuclear copper(II) compounds (1D and 2D, respectively) based on syn-anti carboxylate bridges and additionally on linear monobromo- (in 1) and dibromo-bridging (in 2) motifs. The magnetic properties investigated in the temperature range 1.8-300 K reveal the occurrence of strong antiferromagnetic coupling (J1 = â102.5 cmâ1) through the single bromo-bridge in 1. For 2 a weak ferromagnetic couplings through the syn-anti carboxylate (zJâ²Â = 1.35 cmâ1) and dibromo-bridges (J = 8.31 cmâ1) were found.
