Crystal structure of ammonium divanadium(IV,V) tellurium(IV) hepta­oxide

The polyhedral building blocks of the layered inorganic network in the mixed-valence title compound, (NH(4))(V(IV)O(2))(V(V)O(2))(TeO(3)), are vertex-sharing V(V)O(4) tetra­hedra, distorted V(IV)O(6) octa­hedra and TeO(3) pyramids, which are linked by V—O—V and V—O—Te bonds, forming double layers ly...

description The polyhedral building blocks of the layered inorganic network in the mixed-valence title compound, (NH(4))(V(IV)O(2))(V(V)O(2))(TeO(3)), are vertex-sharing V(V)O(4) tetra­hedra, distorted V(IV)O(6) octa­hedra and TeO(3) pyramids, which are linked by V—O—V and V—O—Te bonds, forming double layers lying parallel to (100). The presumed Te(IV) lone-pairs of electrons appear to be directed inwards into cavities in the double layers. The charge-balancing ammonium cations lie between the layers and probably inter­act with them via N—H⋯O hydrogen bonds.
