A novel single-stranded helix coordination polymer [Cu(L)(SO4)(H2O)] (L = dihydroglyoxaline sulfide) was synthesized and characterized by single-crystal X-ray diffraction, IR, and TGA analysis. The polymer is an unprecedented 1D helical polymer based on a sulfate bridge and a dihydroglyoxaline sulfide chelating ligand. Both ligands were formed in situ through copper-mediated oxidation of 1,3-imidazolidine-2-thione. The helical chain is interlocked with each other through strong hydrogen bonding interactions to form a 2D sheet, which then stacks together to generate a 3D hydrogen bonding network.
