Zusammenfassung:
The new scandium rhodium boride Sc4Rh17B12 was synthesized by
arc-melting of the elements followed by annealing in inert atmosphere.
The crystal structure of Sc4Rh17B12 was solved using single crystal
X-ray diffraction data. The structure can be described as a
three-dimensional framework formed by trigonal prisms [BRh6] and
[BRh5Sc] with isolated boron atoms inside the prisms and trigonal prisms
[BRh5B] representing the coordination polyhedra of paired boron atoms.
The temperature dependences of the magnetic Susceptibility and specific
resistance of Sc4Rh17B12 revealed that the compound is a Pauli
paramagnet and shows metal-like specific resistance.
