NaCr2BiO6 is Ilmenite-derived structured and crystallizes in the trigonal R3 space group. Na(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. In the second Cr site, Cr(2) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. Bi(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Na(1), one Cr(1), one Cr(2), and one Bi(1) atom. In the second O site, O(2) is bonded to one Na(1), one Cr(1), one Cr(2), and one Bi(1) atom to form a mixture of distorted edge and corner-sharing ONaCr2Bi tetrahedra.
