Three Polyoxovanadoborates Constructed from “Sandwich”-Type {V<sub>10</sub>B<sub>24</sub>}, {V<sub>10</sub>B<sub>28</sub>}, and {V<sub>12</sub>B<sub>32</sub>} Clusters

Three distinct polyoxovanadoborates modified by transition metals, specifically {V<sub>10</sub>B<sub>26</sub>Cd<sub>8</sub>(phen)<sub>12</sub>} (<b>1</b>, phen = 1,10-phenanthroline), {V<sub>10</sub>B<sub>32</sub>Zn<sub>6</sub>} (<b>2</b>), and {V<sub>12</sub>B<sub>32</sub>Cu<sub>2</sub>} (<b>3</b>), have been synthesized under hydrothermal conditions. Compounds <b>1</b>-<b>3</b> feature three unique sandwich-type clusters, namely, {V<sub>10</sub>B<sub>24</sub>}, {V<sub>10</sub>B<sub>28</sub>}, and {V<sub>12</sub>B<sub>32</sub>}, each characterized by toroidal (O═VO<sub>2</sub>)<sub><i>n</i></sub> (<i>n</i> = 10, 12) rings.

Abstract

Three distinct polyoxovanadoborates modified by transition metals, specifically {V<sub>10</sub>B<sub>26</sub>Cd<sub>8</sub>(phen)<sub>12</sub>} (<b>1</b>, phen = 1,10-phenanthroline), {V<sub>10</sub>B<sub>32</sub>Zn<sub>6</sub>} (<b>2</b>), and {V<sub>12</sub>B<sub>32</sub>Cu<sub>2</sub>} (<b>3</b>), have been synthesized under hydrothermal conditions. Compounds <b>1</b>-<b>3</b> feature three unique sandwich-type clusters, namely, {V<sub>10</sub>B<sub>24</sub>}, {V<sub>10</sub>B<sub>28</sub>}, and {V<sub>12</sub>B<sub>32</sub>}, each characterized by toroidal (O═VO<sub>2</sub>)<sub><i>n</i></sub> (<i>n</i> = 10, 12) rings. In the structure of <b>1</b>, two pairs of {Cd(phen)} and {Cd(phen)<sub>2</sub>} units are grafted on the {B<sub>13</sub>} rings from the top and bottom of the {V<sub>10</sub>B<sub>24</sub>} cluster, respectively. Compound <b>2</b> is a 1D polymeric chain consisting of the bridging ligand {ZnO<sub>6</sub>} unit linked to {V<sub>10</sub>B<sub>28</sub>}, which accommodates the {Zn<sub>4</sub>B<sub>4</sub>O<sub>8</sub>} unit. The {V<sub>12</sub>B<sub>32</sub>} cluster in <b>3</b> is interconnected with [Cu(en)<sub>2</sub>]<sup>2+</sup> (en = ethylenediamine) to create the sql layer, which is further stacked in an ABAB sequence to form a 3D supramolecular framework. Additionally, sulfide catalytic oxidation experiments revealed that compound <b>2</b> is an efficient and stable sulfide oxidation catalyst.
