The compound described by Li2CBiAsO7 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded in a 3-coordinate geometry to one O(1), one O(4), 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. As(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 distorted T-shaped geometry to two equivalent Li(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one C(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a distorted L-shaped geometry to one C(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one Bi(1), and one As(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Bi(1) and one As(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to two equivalent Li(1), one Bi(1), and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
