title: catena-Poly[[diaqua-bis-(2-ethyl-1H-imidazole-κN(3))cadmium]-μ-sulfato-κ(2)O:O'].
abstract: In the title one-dimensional coordination polymer, [Cd(SO(4))(C(5)H(8)N(2))(2)(H(2)O)(2)](n), the Cd(II) atom (site symmetry 2) is coordinated by two sulfate O atoms, two water mol-ecules and two 2-ethyl-imidazole ligands in a distorted cis-CdN(2)O(4) octa-hedral geometry. The water mol-ecules have a cis disposition. The bridging sulfate ions (site symmetry 2) link the Cd(II) ions into a polymeric chain extending along [001]. The chains are linked by N-H⋯O and O-H⋯O hydrogen bonds. The terminal -CH(3) group of the ligand is disordered over two orientations in a 0.61 (5):0.39 (5) ratio.
