Xu Department of Chemistry, Yancheng Teachers University, Yancheng, Jiangsu 224002, P. R. China E-mail: xxjyctu@gmail.com Received Februaru, 22, 2014 Revised — April, 07, 2014 A two-dimensional Ni(II) complex {[Ni(BTX)(SDBA)(H2O)]0.29H2O}n (1) (BTX = 1,4bis(1,2,4-triazol-1-ylmethyl)-benzene, H2SDBA = 4,4-sulfonyldibenzoic 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 two-dimensional polymer containing 28-membered rings based on the rhomboid subunit [Ni2(C14H8O6S)2] with a Ni—Ni separation of 12.923 Е. <...> The thermal stability and magnetic property of the title complex are briefly investigated. <...> It is well-known that the construction of MOFs is usually influenced by several factors in the self-assembly process, such as organic ligands, solvents, metal atoms, and so on [ 6, 7 ]. <...> Among these factors, the organic ligands play a key role in directing the ultimate architectures of compounds. <...> The main stream method to construct coordination polymers is to utilize carboxylatecontaining and multidentate N-donor ligands. 4,4-Sulfonyldibenzoic acid (H2SDBA) as a semi-rigid V-shaped dicarboxylate ligand is a very versatile ligand for the construction of novel MOFs [ 8—13]. <...> Meanwhile, 1,4-bis(1,2,4-triazol-1ylmethyl)-benzene (BTX) as a flexible bis(triazole) ligand can adopt different conformations depending on the relative orientation of its CH2 groups [14—19 ]. <...> However, to the best of our knowledge, coordination polymers constructed from H2SDBA and BTX ligands have not been documented so far. <...> Here, we have selected H2SDBA and BTX as organic ligands, generating the title new Ni(II) coordination polymer {[Ni(C12N6H12)(C14H8O6S)(H2O)]0.29H2O}n (1), the crystal structure of which we now report. <...> The 1,4-bis(1,2,4-triazol-1-ylmethyl)-benzene (BTX) ligand was synthesized according to the literature method [ 14 ]. <...> The crystal structures were determined on a Siemens (Bruker) SMART CCD diffractometer using monochromated MoKh radiation (y = 0.71073 Е) at 296 K. A total of 9774 reflections were collected in the range of 2.02 25.50, out <...>
