Coordination versatility of 2,2 '-(ethylenedioxy)bis(ethylamine) in new mono- and polynuclear metal(II) complexes of saccharinate: Synthesis, characterization and crystal structures
Özet
The reaction of [M(sac)(2)(H2O)(4)]center dot 2H2(O) (M = Ni-II Cu-II, Cd(II)a nd sac = saccharinate) with 2,2'(ethylenedioxy)bis(ethylarnine) (edbea) resulted in [Ni(edbea)(sac)(2)]center dot 2H(2)O (1) [Cu(edbea)(sac)(2)] (2), [Cu(g-edbea)(sac)(2)](n) (3) and [Cd(edbea)2](sac)2 (4), which have been characterized by elemental analyses, magnetic measurements, FT-IR and EPR (for 3) spectroscopies, thermal analysis, magnetic properties (for 1 and 3) and X-ray diffraction methods. The edbea ligand display different coordination modes in the present complexes. For example, 1 and 2 it acts a tridentate way, while it exhibits a mu-N/O bidentate bridging mode between the copper centers in 3. On the other hand, the geometry of 4 eight-coordinated by two tetradentate edbea ligands is the bicapped trigonal prism structure in which S(degrees) value is the smallest. The EPR spectrum of 3 showed that the local geometry of Cu(II) ion has an elongated rhombic coordination. Complexes 1 and 3 exhibited a paramagnetic behavior as expected, but complex 1 displayed an antiferromagnetic interaction at low temperatures. (C) 2014 Elsevier Ltd. All rights reserved.
