CeNiAsO crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent O(1) atoms. Ni(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing NiAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ni(1) atoms. O(1) is bonded to four equivalent Ce(1) atoms to form a mixture of corner and edge-sharing OCe4 tetrahedra.
