Two compounds in one: The boron-rich ternary compound Gd5Si2B8 represents a new structure type containing independent ordered boron and silicon substructures of compositions GdB4 and Gd3Si2, respectively, alternating along the c direction (see structure). The compound exhibits metallic character, which is supported by theoretical investigations, and has a rather complex magnetic structure.
