Materials Data on LaNiPO by Materials Project
LaNiPO is lead oxide-derived structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one LaO sheet oriented in the (0, 0, 1) direction and one NiP sheet oriented in the (0, 0, 1) direction. In the LaO sheet, La3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All La–O bond lengths are 2.38 Å. O2- is bonded to four equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. In the NiP sheet, Ni2+ is bonded to four equivalent P3- atoms to form a mixture of distorted edge and corner-sharing NiP4 trigonal pyramids. All Ni–P bond lengths are 2.24 Å. P3- is bonded in a 4-coordinate geometry to four equivalent Ni2+ atoms.
