We have synthesized Pb2TiMn using arc-melting technique. We determined crystal structure using X-ray diffraction, we found that it crystallizes in Fm-3m crystall structure with lattice paramater a = 4.9478 A. Magnetic measurements show that it exhibits magnetic transition at T = 225 K and some metamagnetic features at 50 K. At 2 K the magnetization is typical for superconductor, which can be caused by residual Pb expulsions. The magnetization of the sample is weak, and significant atomic disorder can be deduced from thermodynamical properties.
