Аннотация
Two new cadmium(II) complexes, Cd2(L1)2(NCS)2 (1) and Cd2(L2)2(NCS)2 (2), where L1 and L2 are the deprotonated forms of 2-[(3-dimethylaminopropylimino)methyl]-6-ethoxyphenol and 2-methoxy-6-[(pyridin-2-ylmethylimino)methyl]phenol, respectively, have been isolated as crystalline products and characterized by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction method. Both compounds are structurally similar and are phenolate-O-bridged dinuclear cadmium(II) complexes. Each Cd(II) cation in the complexes is octahedrally coordinated. The Cd…Cd distances in (1) and (2) are 3.618(2) and 3.571(2) Å, respectively.
