Abstract
Solide state reactions lead to the hitherto unknown compound Ba4CoTa10O30. X-ray single crystal work (space group C 142v -Amm2,a=3.905,b=10.203 andc=14.954 Å) shows, that the octahedron network of Ba4CoTa10O30 is conform to the Na2Nb12O30 F2-Type. On the other hand the occupation of the tunnels is related to the bronze-structure. The different structure types are discussed.
