This article investigates the effect of initial reagent ratios and temperature on the synthesis of a bimetallic copper–cobalt phthalocyanine (Cu–Pc–Co) compound. The synthesis process was carried out within the temperature range of 180–240 °C using different molar ratios of phthalic anhydride (FA), urea (Kar), CuCl₂, and CoCl₂. The results showed that both temperature and the ratio of initial reagents significantly influence the product yield. In particular, the maximum yield of 87,1% was achieved at an FA:Kar:CuCl₂:CoCl₂ ratio of 1:6,0:1:2 and a temperature of 220 °C. Based on graphical analysis, the optimal reaction conditions were determined. These findings demonstrate that controlling synthesis parameters plays an important role in improving the efficiency of bimetallic phthalocyanine production. Infrared (IR) spectral analysis of the synthesized copper–cobalt phthalocyanine compound confirmed the presence of characteristic phthalocyanine ring bonds (–C–N–C–), as well as metal–nitrogen coordination bonds (Cu–N and Co–N).
