Materials Data on LaZnAsO by Materials Project

Abstract

LaZnAsO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. La3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four equivalent O2- atoms. All La–As bond lengths are 3.42 Å. All La–O bond lengths are 2.39 Å. Zn2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing ZnAs4 tetrahedra. All Zn–As bond lengths are 2.59 Å. As3- is bonded in a 8-coordinate geometry to four equivalent La3+ and four equivalent Zn2+ atoms. O2- is bonded to four equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra.
