Ternäre Komplexboride mit ThMoB4-Typ

摘要

Ternary complex borides of formulaMM′B4*have been prepared within the system Th—{V, Mo, W, Re}—B. The crystal structure of these compounds has been determined by means of single crystal photographs of the compounds ThMoB4and ThWB4. ThVB4, ThMoB4, ThWB4, ThReB4were found to be isotypic. The relationship to the crystal chemistry of boron layer structures such as AlB2, YCrB4, and Y2ReB6will be disc
