In the title compound, [Cu(C₂N₃)₂(C₁₃H₁₄N₂)]_n, the Cu^II atom, located on an inversion centre, adopts a distorted octahedral coordination by six N atoms, two from 1,3-di-4-pyridylpropane and four from dicyanamide ligands, with significantly different Cu-N distances. The metal centres are linked in an unusual triple-bridged mode into chains parallel to [101].
