We present quantum chemical investigations on magnetic properties of several Co6On (n=0–9,12) nanoparticles. The results of calculations show, that only Co6, and Co6O8 particles display paramagnetic properties while other nanoparticles investigated reveal diamagnetic ones. The reason of the derivative paramagnetizability is discussed here. Calculations reveal that the stability of these compounds increases with the increase of the number of O atoms. The limit when the future increase of oxygen atoms does not change binding energy per atoms remarkably is found. The reason why the O atoms could stabilize the Co nanoparticles and change magnetic properties of them is discussed
