The effect of chemical pressure (x) on the spin state of iron ions in FexMn1-xS single crystals (0.12≤ x≤0.29) is studied by the method of Mössbauer spectroscopy in the range 4.2-300 K. Features of the formation of the paramagnetic and antiferromagnetic phases for solid solutions are revealed. It was found that when x changes in FexMn1-xS, the Mn2 + cations are replaced by Fe2 + cations in the high-spin state. A decrease in the interionic distances in FexMn1-xS causes a change in the state of Fe2 + ions in the samples at x = 0.25 and 0.29. In the magnetically ordered phase at 4.2 K, the changes in the asymmetry parameter of the electric field gradient tensor (EFG) and the angle between the directions of the magnetic moment and the principal axis of the electric field gradient from 21o in the sample from x = 0.12 to 33o at x = 0.29 were observed.
