X-ray diffraction and magnetic measurements of RNi₅Sn (R = Pr, Nd) compounds are reported. These compounds crystallize in the hexagonal CeNi₅Sn-type structure. Magnetic data indicate that both compounds are antiferromagnet with the Néel temperatures T_N equal to 24 K (R = Pr) and 8.8 K (R = Nd). The magnetic data below T_N suggest the complex magnetic order.
