Abstract A complete solid solution has been found for mixed crystals LaFe2Si2−LaRh2Si2 of the ThCr2Si2-type and a statistical distribution of iron-and rhodium atoms on the 4d sites of the space group I4/mmm. Crystal symmetry, atom order and precise atom parameters have been determined from a single crystal study of LaFe1.6Rh0.4Si2 (R=0.015). Magnetic susceptibilities (1.8〈T〈1100K) are characterized by a temperature independent paramagnetism throughout the solid solution. The iron atoms prove to be in a nonmagnetic state in good agreement with Mössbauer data at 5K and at room temperature, which further confirms a small amount of iron on a second crystallographic site (4e). LaRh2Si2 is not superconducting above 1.5K.
