The structure described by NaV4O10 crystallizes in the orthorhombic Cmcm space group. Na(1) is bonded in a body-centered cubic geometry to four equivalent O(3) and four equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), two equivalent O(2), and two equivalent O(5) atoms. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(2), one O(4), one O(5), and two equivalent O(1) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one V(1) and two equivalent V(2) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one V(2) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one V(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to one V(2) and two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
