We report here transport and magnetic properties of the R2Ir3Sn5 (R = La, Ce, Pr, Nd) system. R2Ir3Sn5 (R = Ce to Nd) crystallizes in orthorhombic structure (Cmc2(1)) while La2Ir3Sn5 forms in orthorhombic U2Co3Si5 (Ibam) structure. Ce2Ir3Sn5 depicts Kondo behavior (Kondo temperature, T-K=271K) accompanied with an antiferromagnetic ordering at 3.5 K. Studies on Pr2Ir3Sn5 and Nd2Ir3Sn5 indicate magnetic ordering below 5K.
