Özet

This work is related to the structural and magnetic properties of the Co(PPh3)Cl-2 metal complex for different sintering times. The structural and physical properties of the complex have been studied by using SEM, EDX, and magnetization techniques. SEM results clearly demonstrate that the grains of the complex are very well connected to each other and tightly packed. Magnetization measurements with respect to magnetic field and temperature show a paramagnetic behavior above 20 K for the all samples. Furthermore, the susceptibility (chi) as a function of temperature indicates a paramagnetic-antiferromagnetic phase transition with a negative value of the Curie-Weiss temperature, theta. In addition, increasing sintering time appears to also enhance the effective magnetic moment, mu(eff).
