We have carried out neutron diffraction experiments on Ce2Ni3Ge5 single crystal. Ce2Ni3Ge5 orders antiferromagnetically below TN = 5 K and exhibits a successive transition at T* = 4.3 K. We have confirmed that the ground state antiferromagnetic structure is characterized with the propagation vector q = [0 1 0]. We have revealed that this magnetic structure stabilizes only below T* = 4.3 K from the simultaneous neutron diffraction and electrical resistivity measurements, contrary to the previously reported neutron powder diffraction result. From the analysis of magnetic reflection intensities, we suggest that the ground state magnetic structure is a canted AF structure, where the moments orient about 20° tilted from the a-axis in the ab-plane. The obtained AF components are 0.45 μB/Ce along the a-axis and 0.15 μB/Ce along the b-axis. It is suggested that the high temperature phase is characterized with another magnetic phase having a different propagation vector, which is not determined in the present study.
