| Abstract: | Preparation and Crystal Structure of New AM2X2 Compounds in the Systems Earthalkali Metal/Platinum Metal/Germanium . Four new ternary compounds in the systems earthalkali metal/platinum metal/germanium have been prepared and characterised by single crystal X-ray investigation. BaRu2Ge2 crystallizes orthorhombically, space group Fddd, a=634.4(1) pm, b=1 056.5(3) pm, c=1 273,1(3) pm. SrRu2Ge2 (a=430.6(1) pm, c=1 030.3(2) pm), BaRh2Ge2 (a=418.9(5) pm, c=1 175.7(10) pm) and SrRh2Ge2 (a=418.3(3) pm, c=1 071.8(6) pm) crystallize in the ThCr2Si2-type structure (tetragonal, space group I4/mmm). |
