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 lime sizzler firebush for sale AsV atoms are tetrahedrally coordinated and form an As2O7 group.The MoVI atom is may pride peach tree 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.
