title: Ethyl-enediammonium tetra-aqua-disulfato-cadmate.
abstract: The crystal structure of the title compound, [NH(3)(CH(2))(2)NH(3)][Cd(SO(4))(2)(H(2)O)(4)], consists of [Cd(SO(4))(2)(H(2)O)(4)](2-) anions that are built from octa-hedral Cd(H(2)O)(4)O(2) and SO(4) tetra-hedral units linked by corner sharing. The ethyl-ene-diamminium cations are linked to the anions via N-H⋯O hydrogen bonds. The asymmetric unit contains one-half of the compound, the other half being related to the first by an inversion centre. The crystal structure presents alternate stacking of the inorganic and organic layers along the crystallographic b axis. The structure cohesion and stability is further assured by O(water)-H⋯O hydrogen bonds.
