Non-centrosymmetric Na(3)Nb(4)As(3)O(19)

A new non-centrosymmetric compound, tris­odium tetra­niobium triarsenic nona­deca­oxide, Na(3)Nb(4)As(3)O(19), has been synthesized by a solid-state reaction at 1123 K. The structure consists of AsO(4) tetra­hedra and NbO(6) octa­hedra sharing corners to form a three-dimensional framework containing...

description A new non-centrosymmetric compound, tris­odium tetra­niobium triarsenic nona­deca­oxide, Na(3)Nb(4)As(3)O(19), has been synthesized by a solid-state reaction at 1123 K. The structure consists of AsO(4) tetra­hedra and NbO(6) octa­hedra sharing corners to form a three-dimensional framework containing two types of tunnels running along the c axis, in which the sodium ions are located. Na(+) cations occupying statistically several sites, respectively, are surrounded by seven, six and four O atoms at distances ranging from 2.08 (1) to 2.88 (4) Å. The title structure is compared with those containing the same groups, viz. M (2)XO(13) and M (2) X (2)O(17) (M = transition metal, and X = As or P).
