Physical properties of the Tm5Ni2In4 compound have been investigated by means of magnetometric, calorimetric as well as neutron diffraction measurements. The compound crystallizes in the orthorhombic Lu5Ni2In4-type crystal structure (space group Pbam, No. 55). The reported results indicate that the sample exhibits an antiferromagnetic ordering below T-N = 4.1 K. The Tm3+ ions occupy three crystal positions within unit cell: one 2a site and two 4g sites. Analysis of neutron diffraction data collected at T = 1.5 K, together with group theory symmetry analysis predictions show that Tm magnetic moments form a non-collinear magnetic structure described by the propagation vector k = [0,1/2,1/2]. The magnetic moments lie in the (0 0 1) plane.
