The structure described by NaVCAsO7 crystallizes in the monoclinic P2_1 space group. Na(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. V(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(7) atom to form VO6 octahedra that share corners with four equivalent As(1)O4 tetrahedra. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. As(1) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form AsO4 tetrahedra that share corners with four equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-48°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Na(1), one V(1), and one C(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Na(1), one V(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one As(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Na(1), one V(1), and one As(1) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Na(1), one V(1), and one As(1) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one V(1) and one As(1) atom. is represented by the CIF card [CIF]
