Abstract: The asymmetric unit of the title compound, [Cd(C₇H₄NO₃S)₂(C₈H₂₂N₄)]·0.25H₂O, consists of two [Cd(sac)₂(paen)] molecules [sac is saccharinate (C₇H₄NO₃S) and paen is N,N'-bis(3-propylamine)ethylenediamine (C₈H₂₂N₄)], and a partial- occupancy water molecule. Each Cd^II ion is octahedrally coordinated. The equatorial plane of the octahedron is formed by N atoms of the paen ligands, and the axial positions are occupied by the N atoms of the sac ligands. In one of the molecules, the sulfonyl group of a sac ligand is disordered over two different orientations, with site-occupancy factors of 0.83 and 0.17. N-HO hydrogen bonding is observed between the independent molecules. Neighbouring [Cd(sac)₂(paen)] units are linked by N-HO hydrogen bonds into chains running parallel to the a axis.
