Hydrogenating properties of complex rhenidm(VLI) oxides with perovskite structure

Rhenium oxides with perovskite structure of the general formula\(Ba_2 B_{{1 \mathord{\left/ {\vphantom {1 3}} \right. \kern-\nulldelimiterspace} 3}} III\square _{{2 \mathord{\left/ {\vphantom {2 3}} \right. \kern-\nulldelimiterspace} 3}} \operatorname{Re} ^{VII_{O_6 } } \) where BIII=Y and Sm, and Ba3LaZnReW□O12 containing Re(VII), exhibit catalytic activity in hydrogenation of ethyl acetate.
