Structure-Directing Self-Assembly, Structures and Characterization of Four d⁰‑Transition Metal Oxide/Fluoride Compounds Constructed with Imidazole/1-Methylimidazole/1-Vinylimidazole and Copper(II)/Zinc(II)

Four d⁰ transition metal oxide/fluoride compounds of V­(V), Mo­(VI), and Ti­(IV), with the “2D layer”, “1D zigzag chain”, “1D linear chain”, and “0D cluster” structures, have been hydrothermally synthesized, by the structure-directing self-assembly of Meimi/Viimi/imi ligands, and other transition metal Zn­(II)/Cd­(II) ions. The structure-directing property of d⁰ transition metal oxide/fluoride anions is responsible for the tunable syntheses of novel inorganic solids with structural diversities, while the distortion of the d⁰ transition metal oxide/fluoride polyhedrons, owing to the second-order Jahn–Teller (SOJT) effect, is the key to engineering the structure-directing property.
