摘要：

Neutron powder diffraction investigations on Ce2Ni3Ge5 have been carried out. This compound adopts the U2Co3Si5-type structure (Ibam space group) with only one crystallographic site available for Cc atoms. Magnetisation measurements indicate that Ce2Ni3Ge5 undergoes two anti ferromagnetic transitions at low temperature, at T-N1 = 4.8(2) K and T-N2 = 4.2(2) K, respectively. From our neutron diffraction experiments, only one transition is evidenced, below T-N1, Ce2Ni3Ge5 is a collinear antiferromagnet with magnetic moments parallel to the a-axis and equal to 0.4(1) mu(B)/Ce at T = 1.4 K.
