Boron addition to RPd<SUB>3</SUB> compounds (R = rare earth)

It is observed that boron can be alloyed with RPd<SUB>3</SUB> (R = rare earth) compounds to yield alloys of the type RPd<SUB>3</SUB>B<SUB>x</SUB>, where x typically ranges from 0 to 1. Addition of boron does not change the structure type but merely results in lattice expansion. The most likely position for boron is the body centered position. In CePd<SUB>3</SUB> and EuPd<SUB>3</SUB> addition of boron causes a change in the valence state of the rare earth ion
