Among reduced ternary transition metal oxides, tantalates are rare, even though interesting electronic properties might be expected. Here, we report on new reduced alkaline earth tantalates Ca2Ta2O6F, Sr3-xTa5O15, and Ba2Ta15O32 grown under vacuum conditions and high temperatures. These reduced ternary tantalates are isostructural with known reduced ternary niobates, indicating a strong similarity of the crystal chemistry between the two Systems.
