In the search for potential ferroelectric materials, molecular‐based one‐, two‐ and three‐dimensional cadmium(II) organic–inorganic compounds have been of interest as they often display solid–solid phase transitions induced by a variation in temperature. A new cadmium dicyanamide complex, poly[4‐dimethylamino‐1‐ethylpyridin‐1‐ium [tri‐μ‐dicyanamido‐κ 6 N 1 : N 5 ‐cadmium(II)]], {(C 9 H 15 N 2 )[Cd(C 2 N 3 ) 3 ]} n , was synthesized by the reaction of 4‐dimethylamino‐1‐ethylpyridin‐1‐ium bromide, cadmium nitrate tetrahydrate and sodium dicyanamide in aqueous solution. In the crystal structure, each Cd II cation is octahedrally coordinated by six terminal N atoms from six anionic dicyanamide (dca) ligands. Neighbouring Cd II cations are linked together by dicyanamide bridges to form a two‐dimensional coordination polymer. The organic cations are not involved in the formation of the supramolecular network.
