摘要：

The new ternary transition metal borides Mn3-xIr5B2+x (0 <= x <= 0.5) and Mn2IrB2 were synthesized from the elements under high temperature and high-pressure/high-temperature conditions. Both phases can be synthesized as powder samples in a radio-frequency furnace in argon atmosphere. High-pressure/high-temperature conditions were used to grow single-crystals. The phases represent the first ternary compounds within the system Mn-Ir-B. Mn3-xIr5B2+x (0 <= x <= 0.5) crystallizes in the Ti3Co5B2 structure type (P4/mbm; no. 127) with parameters a=9.332(1), c=2.896(2)angstrom, and Z=2. Mn2IrB2 crystallizes in the beta-Cr2IrB2 crystal structure type (Cmcm; no. 63) with parameters a=3.135(3), b=9.859(5), c=13.220(3)angstrom, and Z=8. The compositions of both compounds were confirmed by EDX measurements and the compressibility was determined experimentally for Mn3-xIr5B2+x and by DFT calculations for Mn2IrB2.
