The molecular and crystal structures of 1-(2-methoxyphenyl)-1,4-dihydro-5 H -tetrazole-5-thione (L) and its complex with cadmium(II) ( II ) are studied by X-ray diffraction analysis (CIF files CCDC nos. 1567109 (L) and 1547252 ( II )). Free ligand L is nonplanar thione. The dihedral angle between the tetrazole and benzene cycles is 85.21(7)°. These cycles form centrosymmetric dimers in the crystal by two hydrogen bonds N–H···S. The dimers contain the central planar eight-membered ring {S=C–N–H···S=C–N–H···}. Complex II has a chain structure of the composition [(C 8 H 7 N 4 OS) 2 Cd] n . The coordination mode of the Сd(II) atom is a distorted tetrahedron consisting of two nitrogen atoms and two sulfur atoms of four ligands L. The 1D chains contain the eight-membered rings {←S=C–N–Cd ← S=C–N–Cd} in the boat conformation. Weak intermolecular hydrogen bonds C–H···N are observed between the adjacent 1D chains along the c axis in the crystal.
