Özet

mu-2,2'-Azobispyridinebis[2,2'-azobispyridinesalicylato(O)-salicylato(O,O') cadmium(II), (mu-abpY)[Cd(HsaI)(2)(abpy)](2) (I) was synthesized and characterized by IR and UV/Vis spectroscopy, thermal analysis, and X-ray diffraction techniques. Two abpy ligands and two salicylato ligands coordinate to the Cd2+ ion in a monocapped trigonal-prismatic arrangement. The capping atom is the N3 atom. One of the two abpy ligands behaves as a s-frame bridging ligand and adopts a s-cis/E/s-cis conformation, whereas the other one adopts as a s-cis/E/s-trans conformation. One of the two salicylato ligands acts as a monodentate ligand, which coordinates with the carboxylate oxygen atom, whereas the other one adopts bidentate coordination through two carboxylate oxygen atoms. The hydroxy groups of salicylato ligands, which coordinate in a monodentate fashion, are disordered over two positions, with occupancies of 0.52 for group A and 0.48 for group B. The decomposition reaction takes place in the temperature range 20-1000 degrees C under nitrogen. Thermal decomposition of the title complex proceeds in two stages.
