The crystal structure of Ce2Ni2Sn has been investigated by single-crystal X-ray diffractometry. This stannide adopts an orthorhombic structure related to the W2CoB2 type (space group, Immm), the unit cell parameters being a = 0.439 36(9) nm, b = 0.573 96(9) nm and c = 0.859 67(13) nm. The magnetization and electrical resistivity measurements reveal that Ce2Ni2Sn orders antiferromagnetically at TN = 4.7 K. This study shows that the Kondo effect plays an important role in the physical properties of Ce2Ni2Sn.
