New intermetallic compounds in the RE–Zn–Al systems and their crystal structure

New intermetallic compounds in the RE–Zn–Al systems and their crystal structure

Crystal structures of some new compounds have been determined using X-ray powder data. The intermetallic compounds YbZn 1.75Al 2.25, SmZn 1.62Al 2.38, NdZn 2.34Al 1.66 have the BaAl 4-type structure (s.g. I4/ mmm). Other compounds adopt the La 3Al 11-type structure (s.g. Immm): Y 3Zn 3.2Al 7.8, Gd 3...

Zusammenfassung:Crystal structures of some new compounds have been determined using X-ray powder data.
