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.
