摘要：

Single crystals of FeRh6B4 were synthesized by arc-melting the elements in a water-cooled copper crucible under an argon atmosphere. The new silver-like compound, structurally characterized by single-crystal X-ray analysis, crystallizes in the hexagonal Th7Fe3 structure type (space group P6(3)mc, no. 186, Z = 2; a 7.4135(6) angstrom, c = 4.7168(6) angstrom, R, = 0.040, wR(2) = 0.083 for all 376 reflections and 21 parameters). The structure consists of layers of boron-centered trigonal prisms of rhodium/iron atoms and one-dimensional strings of face-sharing octahedral Rh-6 clusters.
