The conducting oxy salt Ag(AgO)NO has been electrodeposited onto highly oriented conducting oxides of Tl0 and PbTl(,O. T1O was grown in a  texture while the mixed oxide PbTlO was grown with two different thickness-dependent textures of  and . The orientation of the Ag(AgO)NOcrystals with respect to the substrate surface was determined by X-ray diffraction. The face-centered-cubic Ag(AgO)NO crystals deposited on body-centered-cubic T10 and face-centered-cubic Pb„TlO followed the orientation of these prelayers. However, Ag(AgO)NO electrodeposited onto polycrystalline 430 stainless steel had a nearly random orientation. The lattice mismatch is 6.6% between T1O and Ag(AgO)N0, and it is 7.8% between Ag(AgO)N0 and the doubled unit cell edge length of PbTlO. It was also found that PbTl(,O undergoes a transition from a body-centered-cubic to a face-centered-cubic Bravais lattice at a lead content (determined on a metals-only basis) of greater than 40 atom %. © 1992, American Chemical Society.
