<p>A method for synthesis of nickel nanoparticles in a magnetic nickel phthalocyanine anions matrix has been developed.<br>
The method is based on intercalation of potassium atoms to the nickel phthalocyanine (NiPc) polycrystalline powder at<br>
300°C. The structure of (K2NiPc) was investigated by using high-resolution transmission electron microscopy<br>
(HRTEM), X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) spectroscopes. Magnetic properties<br>
were studied by SQUID magnetometry and magnetic resonances methods. It is revealed that the resultant compound<br>
contains of 1 wt% Ni nanoparticles with the average size of 15 nm. The measured values of the magnetization and<br>
absorption of the ferromagnetic resonance considerably exceed the magnetism which can be attributed to metallic Ni<br>
nanoparticles. The obtained results indicate the presence of room temperature molecular ferromagnetism caused by<br>
anionic molecules of NiPc.</p>
