Title: Materials Data on LaCoAsO by Materials Project

Abstract

LaOCoAs is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one CoAs sheet oriented in the (0, 0, 1) direction and one LaO sheet oriented in the (0, 0, 1) direction. In the CoAs sheet, Co2+ is bonded to four equivalent As3- atoms to form a mixture of corner and edge-sharing CoAs4 tetrahedra. All Co–As bond lengths are 2.32 Å. As3- is bonded in a 4-coordinate geometry to four equivalent Co2+ atoms. In the LaO sheet, La3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All La–O bond lengths are 2.39 Å. O2- is bonded to four equivalent La3+ atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra.
