“…The Pr compound required the addition of Os metal to the reaction mixture to act as a sacrificial reductant to preserve the +3 oxidation state for Pr. LuNaPd 6 O 8 (Figure 23)112 was obtained from the dissolution of Lu 2 O 3 and Pd(NH 3 ) 2 Cl 2 or Pd metal in a NaOH melt at 700 °C; the black cubic crystals were isolated by dissolving the flux in water. Other palladates, such as LnKPdO 3 (Ln=La, Pr, Nd, Sm, Eu, Gd),113 were grown as golden‐brown needles from the early rare‐earth oxides and Pd metal in a KOH melt at 750 °C.…”

“…The oxidation state of palladium in these compounds strongly depends on the synthesis technique. While compounds of divalent palladium, such as Ba 2 PdO 3 [1], MPd 3 O 4 (MQCa, Sr, Cd) [2,3] and Lu 0.5 Na 0.5 Pd 3 O 4 [4] have been prepared by a conventional solid-state reaction or hydroxide flux method, a high-pressure technique was applied to synthesize complex oxides containing Pd in higher oxidation states, such as LnPd 2 O 4 (LnQLa, Pr, Nd, Gd, Y) [5], LaPdO 3 [6], Zn 2 PdO 4 [7] and M 4 PdO 6 (MQCa, Sr) [8].…”

“…Die Pr‐Verbindung erforderte die Zugabe von Os‐Metall als Reduktionsmittel, um den Oxidationszustand +3 bei Pr aufrechtzuerhalten. LuNaPd 6 O 8 (Abbildung 23)112 wurde durch Auflösen von Lu 2 O 3 und [Pd(NH 3 ) 2 Cl 2 ] oder Pd‐Metall in einer NaOH‐Schmelze bei 700 °C erhalten; die schwarzen kubischen Kristalle wurden nach Auflösen des Flussmittels in Wasser isoliert. Andere Palladate wie LnKPdO 3 (Ln=La, Pr, Nd, Sm, Eu, Gd)113 wurden als goldbraune Nadeln ausgehend von frühen Seltenerdoxiden und Pd‐Metall in einer KOH‐Schmelze bei 750 °C hergestellt.…”
