[VO(SeO(3))(H(2)O)(2)].0.5H(2)O.
In poly[[diaquaoxido[mu(3)-trioxidoselenato(2-)]vanadium(IV)] hemihydrate], {[VO(SeO(3))(H(2)O)(2)].0.5H(2)O}(n), the octahedral V(H(2)O)(2)O(4) and pyramidal SeO(3) building units are linked by V-O-Se bonds to generate ladder-like chains propagating along the [010] direction. A network of O-H...O hydrogen bonds helps to consolidate the structure. The O atom of the uncoordinated water molecule lies on a crystallographic twofold axis. The title compound has a similar structure to those of the reported phases [VO(OH)(H(2)O)(SeO(3))](4).2H(2)O and VO(H(2)O)(2)(HPO(4)).2H(2)O.
