The perovskite structure, ABX₃: (a) the cubic unit cell outlined in blue, emphasizing the coordination geometry of the A (12-fold) and B (6-fold octahedral) cations to X; (b) the projection representation of the unit cell; (c) the same structure, emphasizing the octahedral coordination of the B sites and description of the structure as linked BX₆ octahedra; (d) the relationship of the perovskite structure to a close-packed arrangement of A and X (arrowed) with B in octahedral holes; the unit cell outlined is the same as that in (a).
