CORRIGENDUM - Chemistry of layered d-metal pnictide oxides and their potential as candidates for new superconductors

The description of the two types of layers in our article is inaccurate. All the [M2Pn2] and [M2Ch2] (M = d-metal; Pn = pnictogen; Ch = chalcogen) layers, which were described as 'fluorite-type', consist of square nets of M atoms coordinated tetrahedrally by Pn (anion) or Ch (anion) alternately above and below the net centers. This arrangement of cations and anions is actually anti-fluorite type, not fluorite-type. Similarly, all the [Ln2O2] (Ln = rare earth atom) layers that were originally described as 'anti-fluorite-type' consist of square nets of O (anion) coordinated tetrahedrally by Ln (cation) alternately above and below the net centers. This arrangement is actually fluorite-type, not anti-fluorite-type. The schematics of the structures are correct. The authors regret the error.
