Positron lifetime measurements were carried out on [FexZn1-x(Ptz)6](BF4)2 single crystals in the temperature range of 72-300 K. Complementary Doppler broadening spectra were also recorded at room temperature. The probability of the formation of ortho-positronium (o-Ps) (lifetime 500-1400 ps) was found to be between 10-30%. It was established that the electron spin state transformation can be monitored by positron lifetime spectroscopy also in the solid state.
