Abstract

The isotypic compounds CaRh2B2 and CaIr2B2 were prepared and investigated by X-ray methods. They crystallize orthorhombic in space group Fddd-D2h 24 with lattice constants CaRh2B2: a = 1060.6 ± 0.4 pm, b = 924.0 ± 0.4 pm, c = 583.2 ± 0.2 pm. CaIr2B2: a = 1072.7 ± 0.4 pm, b = 925.7 ± 0.4 pm, c = 587.7 ± 0.2 pm. The structure contains isolated boron-atoms and can be derived from the CeCo3B2- or CaCu5-type of structure, respectively.
