An electron diffraction and bond valence sum study of the space group symmetries and structures of the photocatalytic 1:1 ordered A2InNbO6 double perovskites (A = Ca2+, Sr2+, Ba2+)

Ting, Valeska; Liu, Yun; Withers, Raymond; Krausz, Elmars


A careful investigation has been carried out into the space group symmetries, structures and crystal chemistries of the 1:1 B-site ordered double perovskites A2InNbO6 (A=Ca2+, Sr2+, Ba2+) using a combination of bond valence sum calculations, powder XRD and electron diffraction. A recent investigation of these compounds by Yin et al. reported a random distribution of In3+ and Nb5+ ions onto the perovskite B-site positions of these compounds and hence Pm3̄m (a=ap, subscript p for parent...[Show more]
