Materials Data on GdFeAsO by Materials Project
Abstract
GdFeAsO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Gd3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four equivalent O2- atoms. All Gd–As bond lengths are 3.33 Å. All Gd–O bond lengths are 2.29 Å. Fe2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing FeAs4 tetrahedra. All Fe–As bond lengths are 2.60 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Gd3+ and four equivalent Fe2+ atoms. O2- is bonded to four equivalent Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra.
