In the title cadmium chloride salt, (C 3 H 5 N 4 O 2 ) 4 [CdCl 6 ]·4H 2 O, the asymmetric unit comprises two N‐protonated 5‐amino‐3‐carboxy‐4 H ‐1,2,4‐triazol‐1‐ium cations, half a [CdCl 6 ] 4− anion and two molecules of water. The Cd 2+ cation is located on a centre of inversion and is coordinated by six chloride anions, forming a distorted octahedron. In the crystal structure, alternating layers of cations and anions are arranged along the [101] direction, forming a three‐dimensional supramolecular network via a combination of hydrogen‐bonding and aromatic stacking interactions.
