The reaction of Cu(ClO4)2·6H2O, imidazole (ImH), and ethylenediamine (en) in a 1 : 2 : 1 ratio afforded in high yield dark-blue single-crystals of [(en)Cu(ImH)2](ClO4)2, 1, which can be used after deprotonation as a building block for heterometallic ferrimagnetic chains. The structural and electronic properties of 1 were examined by X-ray crystallography, FTIR, ESI-MS, electrochemistry, UV/vis/...
