Crystal and magnetic properties of three equiatomic ternary RERhSn compounds (where RE = Ce, Nd, Gd) have been studied by means of X-ray diffraction, ac, and dc magnetic susceptibility measurements, as well as using Mössbauer spectroscopy with 119Sn and 155Gd resonances. CeRhSn does not order magnetically down to 2 K while NdRhSn undergoes ferromagnetic transition at TC = 10.3 K and GdRhSn orders antiferromagnetically below TN = 16 K. Our CeRhSn and NdRhSn samples become superconductive below 6.5 K and 6.9 K, respectively.
