A 1D Helical Ni(II) Coordination Polymer Based on Butylphenyl Imidazole Dicarboxylate

<div><p>Solvothermal reaction of nitrate salt with a multifunctional organic ligand, 2-(<i>p-tert-</i>butylphenyl)-1<i>H</i>-imidazole-4,5-dicarboxylic acid (<i>p</i>-H<sub>3</sub>BuPhIDC), leads to a novel 1-D helical chain coordination polymer, {[Ni<sub>4</sub>(μ<i><sub>2</sub></i>-<i>p</i>-HBuPhIDC)<sub>4</sub>(H<sub>2</sub>O)<sub>4</sub>]·H<sub>2</sub>O}<sub>n</sub> (1), which has been characterized by single-crystal X-ray diffraction, spectroscopy, and elemental analysis. The thermal and photoluminescent properties of polymer 1 have been investigated as well.</p></div>
