Croconato-bridged copper(II) complexes: synthesis, structure and magnetic characterization
Popis výsledku v původním jazyce
Three croconato-bridged Cu(II) complexes were synthesized and structurally characterized including dinuclear [Cu-2(Et(4)dien)(2)(mu(1,2,3,4)-C5O5)](ClO4)(2)center dot 3H(2)O (1) and [Cu-2(pmap)(2)(mu(1,2,3,4)-C5O5)](ClO4)(2)center dot 2H(2)O (2) and the 1D coordination polymer {[Cu(dmpzp)(mu(1,2,3,4)-C5O5)]center dot H2O}(n) (3), where Et(4)dien = N, N',N '',N ''-tetraethylethylenetriamine, pmap = bis(2-(2-pyridyl)ethyl)-(2-pyridylmethyl)amine and dmpzp = 1-(2-methylpyridyl)-3,5-dimethyl-1-H-pyrazole. The synthesized complexes were further characterized by a single crystal X-ray analysis which revealed the bis-bidentate chelating nature of the mu(1,2,3,4)-croconato ligand with the intra-dimer Cu center dot center dot center dot Cu bond distances ranging from 6.79 to 7.69 angstrom across the bridged croconate. The magnetic susceptibility measurements at varying temperatures (1.9-300 K) showed that the complexes exhibit a weak antiferromagnetic (AF) coupling with J values = -2.67 cm(-1) for 1 and 2, and -4.05 cm(-1) for 3. The weak AF coupling was also predicted based on the DFT calculations. The magnetic properties of the complexes are discussed in light of their structures and compared with the previously reported croconato-bridged Cu(II) complexes.
