The intermetallic compound TbRhSn was investigated in detail by X-ray, magnetic susceptibility measurements and 119Sn Mössbauer spectroscopy. This compound undergoes a transition from a paramagnetic to an antiferromagnetic state at TN = 20.8(2) K. The 119Sn Mössbauer spectrum recorded at 4.2 K can be well fitted as a composition of three subspectra with the same intensities, magnitudes of Hhf, ΔEQ, and δis, in agreement with the model of triangular-like antiferromagnetic arrangements of equal magnetic Tb moments lying in the basal ab-plane deduced from neutron diffraction studies (Szytuła et al., J Alloys Compd 244:94–98, 1996).
