1 according to AAS data 2 after 3.5 hours of the reaction; formula of 3 is shown on Fig. 3 weak XRD signal. Size was calculated for only one peak with 2θ = 43.3 value is calculated according to the synthetic procedure On the powder X-ray diffraction patterns of all samples the peaks at 2θ = 43.2 and 50.3 were observed. These peaks correspond to 111 and 200 crystallographic planes of the metallic Cu (Fig. ) [52,53] , thus, metallic Cu was observed in the powder XRD patterns of samples, formed at 300 °C and higher temperatures. It could be concluded that his temperature was already sufficient for the reduction of Cu II by the organic ligands (Phen or DAB).
