Abstract: ⁵⁷Fe Mössbauer and X – ray powder diffraction (XRD) of the alloy system Fe₁₋yCrySb₂ for 0 ≤y ≤ 0.97 at 300K have been studied. XRD patterns of all specimens recorded using FeKα radiation at 300K suggest the presence of single phase orthorhombic crystal structure for this alloy series. The lattice parameters and the unit cell volume increase with the increase in chromium concentration. The ⁵⁷Fe Mössbauer spectra for all the compositions analyzed as a single quadrupole split doublet reveal the paramagnetic character. The increase in the isomer shift and the decrease in the quadrupole splitting with the increase in chromium concentration y for the alloy series have been correlated with the observed structural and bonding properties of the series compositions.
