Abstract
The crystal structure of Ce2Ni2Sn has been investigated by single-crys tal X-ray diffractometry. This stannide adopts an orthorhombic structu re related to the W2CoB2 type (space group, Immm), the unit cell param eters 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 T-N=4.7 K. This study shows t hat the Kondo effect plays an important role in the physical propertie s of Ce2Ni2Sn.
