Two new dicyanamide coordination polymers, {Mn(dmpz)[N(CN) 2 ] 2 } 2 ( 1 ) and {Cu(dmpz)[N(CN) 2 ] 2 } 2 ( 2 ) (dmpz=3,5‐dimethylpyrazole), were synthesized and characterized by single crystal X‐ray diffraction analysis and IR spectroscopy. In 1 and 2 the metal ions have two different coordination modes, where one is coordinated to four dicyanamide anions and two monodentate dmpz molecules to form a slightly distorted octahedral geometry, while the other adopts octahedral geometry, surrounded by four nitrile N atoms and two amide N atoms of the dicyanamide anions. Both complexes contain two alternating chains that are parallel to each other.
