In the crystal structure, two types of Cd<sup>II</sup> atoms are observed in distorted octahedral coordination environments. One type of Cd<sup>II</sup> atom is coordinated by two O atoms from the carboxylate group of the 4‐(dimethylamino)pyridinium‐1‐acetate ligand and by two N atoms and two S atoms from four different thiocyanate ligands, while the second type of Cd<sup>II</sup> atom is coordinated by three N atoms and three S atoms from six different thiocyanate ligands. Neighbouring Cd<sup>II</sup> atoms are linked by thiocyanate bridges to form a one‐dimensional zigzag chain and a one‐dimensional coordination polymer. Hydrogen‐bond interactions are involved in the formation of the supramolecular network.</p> </abstract>
