摘要：

Single crystals of the new phase TmAlB14 were grown using the high-temperature solution method. The crystal structure of TmAlB14 was refined from X-ray powder diffraction data using the Rietveld method. The structure is of MgAlB14-type with the space group Imma and unit cell parameters a = 5.8212(3) angstrom, b = 10.3837(2) angstrom and c = 8.1762(3) angstrom. The final, conventional R-value and profile R-value are 0.031 and 0.064, respectively. The structure is characterized by a partial occupancy of both metal positions and a splitting of the thulium atomic position.
