The structural, magnetic, lattice, and electronic transport properties of Mn3SnCx compounds were investigated. Variation in carbon content from 0.6 to 1.2 does not change the crystal structure. With the increasing of x, the magnetic order changes from antiferromagnetic to ferromagnetic, and the transition temperature increases. The lattice constant shrinks around magnetic transition temperature when temperature increases. The total behavior of Mn3SnCx in temperature dependence of resistivity is very complex. For some Mn3SnCx, the temperature coefficient of resistivity is negative in the scope of magnetic order temperature. For other Mn3SnCx, the total behavior is metallic-type, and the resistivity appears an abrupt change.
