title: Materials Data on Na2FeO3 by Materials Project

description: Na2FeO3 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one Na2FeO3 sheet oriented in the (1, 1, -2) direction. there are eight inequivalent Na sites. In the first Na site, Na is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are a spread of Na–O bond distances ranging from 1.75–2.37 Å. In the second Na site, Na is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.60 Å) and one longer (1.74 Å) Na–O bond length. In the third Na site, Na is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.60 Å) and one longer (1.72 Å) Na–O bond length. In the fourth Na site, Na is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are a spread of Na–O bond distances ranging from 1.75–2.37 Å. In the fifth Na site, Na is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are a spread of Na–O bond distances ranging from 1.75–2.37 Å. In the sixth Na site, Na is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.60 Å) and one longer (1.74 Å) Na–O bond length. In the seventh Na site, Na is bonded in a distorted linear geometry to two O atoms. There is one shorter (1.60 Å) and one longer (1.73 Å) Na–O bond length. In the eighth Na site, Na is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are a spread of Na–O bond distances ranging from 1.75–2.37 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a 2-coordinate geometry to two O atoms. There is one shorter (1.36 Å) and one longer (1.55 Å) Fe–O bond length. In the second Fe site, Fe is bonded in a 2-coordinate geometry to two O atoms. There is one shorter (1.35 Å) and one longer (1.56 Å) Fe–O bond length. In the third Fe site, Fe is bonded in a 2-coordinate geometry to two O atoms. There is one shorter (1.37 Å) and one longer (1.56 Å) Fe–O bond length. In the fourth Fe site, Fe is bonded in a 2-coordinate geometry to two O atoms. There is one shorter (1.35 Å) and one longer (1.55 Å) Fe–O bond length. There are twelve inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to two Na atoms. In the second O site, O is bonded in a distorted linear geometry to one Na and one Fe atom. In the third O site, O is bonded in a 2-coordinate geometry to two Na atoms. In the fourth O site, O is bonded in a 2-coordinate geometry to one Na and one Fe atom. In the fifth O site, O is bonded in a 2-coordinate geometry to three Na and one Fe atom. In the sixth O site, O is bonded in a 2-coordinate geometry to three Na and one Fe atom. In the seventh O site, O is bonded in a distorted linear geometry to one Na and one Fe atom. In the eighth O site, O is bonded in a 2-coordinate geometry to two Na atoms. In the ninth O site, O is bonded in a 2-coordinate geometry to one Na and one Fe atom. In the tenth O site, O is bonded in a distorted bent 150 degrees geometry to two Na atoms. In the eleventh O site, O is bonded in a 2-coordinate geometry to three Na and one Fe atom. In the twelfth O site, O is bonded in a 2-coordinate geometry to three Na and one Fe atom.
