In the title compound, [Cd(NCS)2(C4H6N4O2)2]n, the CdII cation is located on an inversion center and is coordinated by two N and two S atoms from four SCN− anions and two N atoms from two 3-(1H-tetra­zol-1-yl)propanoic acid (Htzp) ligands in a distorted octa­hedral geometry. The SCN− anions bridge the CdII cations into a layer structure parallel to (100). A weak intra­molecular C—H⋯N inter­action occurs. The layers are further assembled into a three-dimensional supra­molecular structure via classical O—H⋯O hydrogen bonds.
