The compounds Bi{sub 4}V{sub 2{minus}x}Ni{sub x}O{sub 11{minus}1.5x}, x {le} 0.35, were prepared by solid state reaction. The {alpha} phase is present at room temperature for x {le} 0.20 and the {gamma} phase is stable for greater Ni concentrations. The oxygen ion vacancies in the x = 0.30 phase exist in the equatorial plane of the V/Ni coordination octahedron. The x = 0.30 phase is paramagnetic. As the Ni concentration decreases the magnetic spin structure gradually changes to that of an amorphous spin glass. At 833 K the ionic conductivity {sigma} = 3.16 {times} 10{sup {minus}2} S cm{sup {minus}1}. The ionic conductivity decreases with increasing Ni concentration.
