Electrical and magnetic properties of some europium ''tungsten bronze'' type compounds were investigated. Europium was confirmed to be in the + 2 oxidation state. Electrical conductivity in europium niobate Eu Nb/sub 2/O/sub 6/ was found to be much higher than in the tantalate Eu Ta/sub 2/O/sub 6/. The presence of electrons on niobium ions in Eu/sub 0/,/sub 60/ NbO/sub 3/ compound considerably increased the electrical conductivity. Two band models derived from Goodenough's for tungsten bronze structure are discussed.
