A unique chain of trinuclear Cu(II) units containing both neutral and anionic N-(pyrimidin-2-yl) acetamide (Haapm, resp. aapm) as a ligand and dicyanamide (dca): Synthesis, characterization, X-ray structure and magnetism of [Cu3(μ-aapm)2(μ-dca)2(Haapm)2

A new trinuclear Cu(II) compound [Cu3(μ-aapm)2(μ-dca)2(Haapm)2](CF3SO3)2, containing the ligands N-(pyridin-2yl)acetamide (Haapm) and dicyanamide (dca) is reported. The dca anions are connected in an end-to-end fashion to a neighboring Cu(II) ion, forming in this way a chain of trinuclear units bridged by two dca anions.
