Xu, J. Wang Department of Chemistry, Yancheng Teachers University, Yancheng, Jiangsu, P.R. China E-mail: wjyctu@gmail.com Received November, 25, 2013 A one-dimensional Cd(II) complex [Cd(Bu2bpy)(tbip)H2O]n (1) (Bu2bpy = 4,4′-di-tert-butyl2,2′-bipyridine, H2tbip = 5-tert-butyl isophthalic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. <...> The single crystal X-ray diffraction analysis reveals that complex 1 is a one-dimensional double chain polymer based on {Cd2(OCO)2} dimeric kernels with a Cd Cd separation of 4.3197(7) Е. <...> The thermal stability and luminescent properties of the title complex are briefly investigated. <...> Considerable efforts have been focused on the rational design and synthesis of coordination polymers not only because of their intriguing structural diversity and new topologies but also due to their potential applications in gas storage, chemical separations, microelectronics, nonlinear optics, heterogeneous catalysis, and so on [ 1—8]. <...> It is well-known that the structure of the coordination polymer is usually influenced by several factors in the self-assembly process, such as organic ligands, solvents, metal atoms, temperature, and so on [ 9—14]. <...> Among these factors, the choice of organic ligands plays a key role in directing the ultimate architectures of the complexes. <...> In recent years, multicarboxylate ligands have been widely used in the construction of coordination polymers because of their diversity in coordination modes and conformations [ 15—17]. 5-tert-Butyl isophthalic acid (H2tbip) as a substituted isophthalate ligands at meta-disposed position 5 is chosen to construct novel coordination polymers mainly because of the steric hindrance and electron-donating properties of the bulky tert-butyl group which can affect the coordination abilities and modes of the carboxylic groups [ 18—22]. <...> However, to the best of our knowledge, coordination polymers constructed from 5-tert-butyl isophthalic acid (H2tbip) and 4,4′-di-tert-butyl-2,2′-bipyridine (Bu2bpy) ligands have not been <...>
