Disodium molybdenum dioxide diarsenate, Na2MoO2As2O7, has been synthesized by a solid-state reaction.The structure is built up from MoAs2O12 linear units sharing corners to form a three-dimensional framework containing tunnels running along the a-axis direction in which the Na+ cations are located.In this framework, the Ball - Nets AsV atoms are tetrahedrally coordinated Football - Protective - Helmets and form an As2O7 group.

The MoVI atom is displaced from the center of an octahedron of O atoms.Two Na+ cations are disordered about inversion centres.Structural relationships between different compounds: A2MoO2As2O7 (A = K, Rb), AMOP2O7 (A = Na, K, Rb; M = Mo, Nb) and MoP2O7 are discussed.
