Oxidopolyborate chemistry
Abstract
<p>[Cu(en){B<sub>6</sub>O<sub>7</sub>(OH)<sub>6</sub>}]<sup>.</sup>3H<sub>2</sub>O (1) (en = 1,2-diaminoethane), obtained as a crystalline solid in low yield (31%) after prolonged standing of an aqueous solution initially containing [Cu(en)<sub>2</sub>](OH)<sub>2</sub> and B(OH)<sub>3</sub> (1:7 ratio), was characterized by thermal analysis (TGA/DSC), <sup>11</sup>B NMR and IR spectroscopy, powder XRD, and single-crystal XRD studies, and magnetic susceptibility measurements. The single-crystal X-ray diffraction revealed that the oxidoborate complex is a 1D coordination polymer with the hexaborate(2-) ligand bridging two hexacoordinate Cu<sup>(II)</sup> centers, in an alternating a fac-tridentate (κ<sup>3</sup>-O) and monodentate (κ<sup>1</sup>-O) arrangement. Cu-O coordination bonds and extensive H-bonding networks promote and stabilize the self-assembly of [Cu(en){B<sub>6</sub>O<sub>7</sub>(OH)<sub>6</sub>}]<sup>.</sup>3H<sub>2</sub>O from the Dynamic Combinatorial Libraries of available reactants. [Cu(en){B<sub>6</sub>O<sub>7</sub>(OH)<sub>6</sub>}]<sup>.</sup>3H<sub>2</sub>O is thermally decomposed to CuB<sub>6</sub>O<sub>10</sub> in air at 700 °C.</p>
