Ternary YbPt2B crystallizes in the non-centrosymmetric hexagonal CePt2B-type structure (space groupP6222). Electrical resistivity, specific heat and magnetic measurements reveal a magnetic instability at5.6 K. Furthermore, a spin-reorientation of presumably a ferromagnetic type occurs around 1.5 K.The behaviour at low temperature is governed by a rather weak Kondo effect, TK 1K, in the presenceof strong crystalline electric field splitting, with a doublet ground state. Besides, the complex magneticbehaviour presumably results from a Dzyaloshinskii-Moriya interaction triggered by the absence ofinversion symmetry in the crystal structure. Scaling according to the de Gennes factor traces backmagnetic ordering in YbPt2B to the Rudermann-Kittel-Kasuya-Yoshida (RKKY) interaction and thesmooth evolution of the lattice constants and the unit cell volume of REPt2B (RE = rare earths) refers tothe 4f 13 electronic configuration of Yb in YbPt2B.
