In this paper, highly crystalline and water dispersible nickel ferrite nanoparticles were synthesised by the hot injection thermolysis of heterometallic pivalate cluster ([Fe2NiO(O2CtBu)6(HO2CtBu)3]) in triethylene glycol (solvent) and polyvinyl pyrrolidone (capping agent) at the boiling point of the solvent (285 °C.( The nanoparticles were characterised by Powder X-ray Diffraction (p-XRD), Transmission Electron Microscopy (TEM) and Selected Area Electron Diffraction (SAED) and Energy Dispersive Spectroscopy (EDS). The p-XRD showed crystalline pure phase of nickel ferrite nanoparticles and TEM revealed a spherical morphology of average size 7.0 ± 0.7 nm. The as synthesised nanoparticles are directly water dispersible without any post modification process.
