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.四类V(V)、Mo(VI)和Ti(IV)的d0过渡金属氧化物/氟化物化合物，分别以“二维层状”、“一维之字形链”、“一维线性链”和“零维簇”结构存在，已通过Meimi/Viimi/imi配体的结构导向自组装及其他过渡金属Zn(II)/Cd(II)离子的协同作用，于水热条件下成功合成。d0过渡金属氧化物/氟化物阴离子的结构导向特性赋予了合成新型无机固体材料的结构多样性，而由二级Jahn-Teller (SOJT) 效应引起的d0过渡金属氧化物/氟化物多面体的畸变则是调控结构导向特性的关键。
