The compound [Cu₄(dpk·OCH₃)₂(N₃)₆]_n [dpk = di-2-pyridylketone] consists of tetranuclear units that repeat in two dimensions. Predominant ferromagnetic interactions are in good agreement with the crystal structure, showing alternating Cu₂(1,1)-azide₂ and Cu₂ (1,1)-azide-oxo bridging units. Rare (1,1,3,3)-azide bridges promote the two-dimensionality and cause the low temperature antiferromagnetism.
