| Abstract: | In polydiaquaoxidoμ3‐trioxidoselenato(2?)]vanadium(IV)] hemihydrate], {VO(SeO3)(H2O)2]·0.5H2O}n, the octahedral V(H2O)2O4 and pyramidal SeO3 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)(H2O)(SeO3)]4·2H2O and VO(H2O)2(HPO4)·2H2O. |
