The crystal structure described by Na2CBiPO7 crystallizes in the monoclinic P2_1/m space group. Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. Bi(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. P(1) is bonded in a tetrahedral geometry to one O(5), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted trigonal pyramidal geometry to two equivalent Na(1), one C(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Na(1), one C(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Bi(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Na(1), one Bi(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Bi(1), and one P(1) atom. is represented by the CIF card [CIF]
