The heat diffusivity D, the electrical resistivity ρ and the thermoelectric power S of tetragonal Mn_{2-x}Cr_{x}Sb single crystals with 0.02 < x < 0.12 have been measured in the temperature range of 90 K < T < 350 K and along different crystal axes. The heat conductivity κ and σ = 1/ρ are anisotropic along the crystal axes a, c with a ratio of 2:1. κ(T) , ρ(T) and S(T) show anomalies at the spin reorientation temperature T_{Rm} of the matrix (M) Mn_{2-x}Cr_{x}Sb, but also at that of the coherent ferromagnetic precipitate (P) Mn_{1.037}Cr_{0.11}Sb, T_{R}_{p} which is assigned to variations in the spin dependent scattering at the M /P interfaces via changes in the relative orientation of the magnetization vectors of matrix and precipitate (spin valve effect).
