Magnetization and electrical resistivity measurements were carried out for polycrystalline Mn_{2}Sb_{1-x}Ge_{x} (0.05 ? x ? 0.2) and Mn_{2}Sb_{1-x}Sn_{x} (0.08 ? x ? 0.15) in magnetic fields up to 16 T in the 4.2?600 K temperature range in order to investigate the magnetic and the electrical properties under magnetic fields. Mn_{2}Sb_{0.95}Ge_{0.05} and Mn_{2}Sb_{0.9}Sn_{0.1} showed a first-order magnetic transition from a ferrimagnetic (FRI) to an antiferromagnetic (AFM) phase in the vicinity of T_{t} = 172 K and 190 K, respectively, with decreasing temperature in a zero magnetic field. With increasing x, T_{C} decreased slightly and T_{t} increased. The electrical resistivity changes abruptly by 87% for Mn_{2}Sb_{0.95}Ge_{0.05} and 43% for Mn_{2}Sb_{0.9}Sn_{0.1} at T_{t}. The magnetic phase diagrams of Mn_{2}Sb_{1-x}Ge_{x} and Mn_{2}Sb_{1-x}Sn_{x} are presented.
