The high-temperature/high-pressure hydrothermal synthesis and X-ray single crystal structure of NaNb{sub 2}AsO{sub 8} are reported. The title compound contains a three-dimensional network of NbO{sub 6}, NbO{sub 5}, and AsO{sub 4} groups, enclosing one-dimensional channels containing seven-coordinate guest sodium cations. UV/visible measurements on NaNb{sub 2}AsO{sub 8} indicate two distinct absorption features at {approximately}285 and {approximately} 360 nm. Crystal data for NaNb{sub 2}AsO{sub 8}:M{sub r} = 410.79, monoclinic, P2{sub 1}/n(No.14), a = 4.8970(6) {angstrom}, b = 8.516(2) {angstrom}, c = 15.075(3) {angstrom}, {beta} = 98.971(6){degrees}, V = 620.98 {angstrom}{sup 3}, Z = 4, R = 5.31%, R{sub w} = 5.15%, 2121 observed reflections (I > 3{sigma}(I)).
