| dc.description.abstractEn | The aluminide CeRuAl with orthorhombic LaNiAl-type structure contains two crystallographically independent cerium sites which both exhibit relatively short Ce–Ru distances, i. e. 280 – 302 pm for Ce1 and 286 – 310 pm for Ce2. Susceptibility measurements show intermediate valence behavior of the cerium atoms (1.19(1) μB per formula unit) and no magnetic ordering down to 2 K. Chemical bonding analysis reveals a non-magnetic ground state and strong Ce–Ru bonding. The Ce–Ru bonding peculiarities of CeRuAl are discussed in line with those of other binary and ternary cerium–ruthenium compounds. | |
