 Abstract: The crystal structures of three (Cr,Ni)4−xTxSi phases (T ​= ​Cu, Fe, Pd) were refined from X-ray powder diffraction data. The compounds crystallize with Au4Al-type structures (Pearson symbol cP20, space group P213): unit-cell parameter a ​= ​0.612718(9) nm for the composition (Cr0.341Cu0.061Ni0.598)4Si, a ​= ​0.612890(5) nm for (Cr0.341Fe0.061Ni0.598)4Si, and a ​= ​0.616219(5) nm for (Cr0.341Pd0.061Ni0.598)4Si. The temperature dependence of the magnetic susceptibility was studied in external fields of up to 7 ​T at temperatures between 1.8 and 400 ​K. The three investigated samples were found to be paramagnets governed by the modified Curie-Weiss law: χ0 ​= ​161⋅ 10−6 emu g-at.−1, μeff ​= ​0.34 μB/atom, θp ​= ​−7(2) K for (Cr0.341Cu0.061Ni0.598)4Si; χ0 ​= ​182⋅ 10−6 emu g-at.−1, μeff ​= ​0.63 μB/atom, θp ​= ​−4(3) K for (Cr0.341Fe0.061Ni0.598)4Si; χ0 ​= ​154⋅ 10−6 emu g-at.−1, μeff ​= ​0.48 μB/atom, θp ​= ​−8(2) K for (Cr0.341Pd0.061Ni0.598)4Si. © 2022 Elsevier Inc.
