Abstract: In the title compound, {(C₁₀H₁₂N₃O₃S)₂[CdCl₄]·H₂O}_n, the Cd^II atom is five-coordinate with a distorted trigonal-bipyramidal geometry formed by chloride ions. The Cd atom and two of the Cl atoms lie on a mirror plane. The cation is protonated on the amino group N atom; it is not coordinated to cadmium, but is hydrogen bonded to the chlorido ligands. Each water molecule bridges two chlorido ligands, generating ring motifs along the -Cd-Cl-Cd- chains. The isoxazole unit and the amide groups are linked through a pair of N-HN hydrogen bonds. The crystal structure is stabilized by N-HO, O-HCl, C-HN, N-HCl and C-HO hydrogen bonds.
