Positron lifetime spectra for Zn(1-x)Mg(x)Se compounds with different magnesium content and different crystal structure have been measured. For all investigated samples positron lifetime component corresponding to divacancy type of defects was found. The decrease in the intensity of this component with increasing magnesium content is due to lowering concentration of divacancies. Slight rise in bulk lifetime with increasing magnesium content, from 251±5 ps to 281±18 ps, was observed.
