Figure 2
Ball-and-stick representation of the asymmetric unit, comprised of two [W4O14]4– building blocks, showing the five-coordinate W1 and W5 atoms. The tip of the tetramer (W4) connects to the next tetramer, which W8 then repeats; the whole asymmetric unit needs to be repeated three times to complete the entire anion. Counter-ions, O atoms of solvent water molecules, and oxygen labels are omitted for clarity. Color code: W in maroon and O in red. |
