The crystals of the first copper(II) ethylenediamine complex containing citrate anion have been prepared and characterized. Despite the archetypical character of the copper(II) ethylenediamine complexes, some structural peculiarities were found to be interesting since they are quite rare even among the mentioned type of the complex compounds i.e. a presence of both mono and diaqua-bis(ethylenediamine)copper(II) cations together in the same crystal structure, intramolecular hydrogen bonding of the citric anion, cis,trans-configuration of the citric anion and the disordered C-C bond of the ethylenediamine molecule in the monoaquabis(ethylenediamine)copper(II) cation, which in fact is a co-existence of two energetically close dd and dk conformers. The Raman as well as FTIR spectra were recorded and discussed. Finally, the magnetic measurements have shown paramagnetic behavior of the prepared complex in a wide range of temperatures.
