The structural and magnetic properties the polycrystalline Ce1-xTbxMn2Si2 (0 <= x <= 1) compounds were studied by means of X-ray powder diffraction, AC susceptibility and differential scanning calorimetry (DSC). All compounds investigated crystallize in the body-centred tetragonal ThCr2Si2-type structure with the space group 14/mmm. Substitution of Tb for Ce leads to a linear decrease of the lattice constants and the unit cell volume. The lattice constants and the unit cell volume obey Vegard's law. At low temperatures, the rare earth sublattice orders and reconfigures the ordering in the Mn sublattice for x >= 0.2. The Neel temperature T-N(Mn) determined by DSC technique increases linearly with increasing Tb content x. The results are collected in the x-T magnetic phase diagram.
