Summary:•A new compound Nd2PtGe3 was succesfully synthetized by an arc-melting method.•Nd2PtGe3 crystallizes in a disordered ternary variant of the AlB2-type structure.•Significant anisotropic broadening of X-ray diffraction peaks was observed.•Cluster glass behavior is seen below 3 K due to disorder and magnetic frustration. In the present study we report a successful synthesis of the new intermetallic compound Nd2PtGe3 by an arc-melting method. The powder X-ray diffraction analysis indicates that this compound crystallizes in an disordered variant of the AlB2-type structure (space group P6/mmm, no. 191) with lattice parameters a = 4.2455 Å and c = 4. 1933 Å. The compound exhibits a cluster-glass transition below Tf = 2.9 K, characterized through ac and dc magnetic susceptibility and heat capacity measurements.
