Fig. 1: Metal-oxygen connectivity of the molecular precursors.

a–c Crystal structures of 1, 2 and 3 (anion only), SMe2 groups of DMSO ligands coordinated to Bi, and all H atoms omitted for clarity. d Scheme of the strategy used to synthesise m-BiVO4 from well-defined molecular precursors (V2O5 by-product not shown). Colour code Bi, purple; V, blue; O, red; and Cl, green.
