Neutron diffraction studies of PrCu2Sn2 and NdCu2Sn2 compounds indicate tha
t both compounds exhibit the tetragonal primitive crystal structure of CaBe
2Ge2-type, PrCu2Sn2 below T-N=3.8 K is an antiferromagnet with a collinear
antiferromagnetic structure of the AFI-type while NdCu2Sn2 is a paramagnet
