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

Solvothermal reaction of nitrate salt with a multifunctional organic ligand, 2-(p-tert-butylphenyl)-1H-imidazole-4,5-dicarboxylic acid (p-H₃BuPhIDC), leads to a novel 1-D helical chain coordination polymer, {[Ni₄(μ₂-p-HBuPhIDC)₄(H₂O)₄]·H₂O}_n (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.
