Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The mixed‐ligand pentaborate, [Cu(C<sub>12</sub>N<sub>2</sub>H<sub>8</sub>)<sub>2</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)][B<sub>5</sub>O<sub>6</sub>(OH)<sub>4</sub>]<bold>·</bold>C<sub>4</sub>H<sub>9</sub>NO (<bold>1</bold>), was synthesized and characterized by single‐crystal X‐ray diffraction, elemental analyses, powder X‐ray diffraction, infrared spectroscopy, and thermogravimetric analysis. Two adjacent [B<sub>5</sub>O<sub>6</sub>(OH)<sub>4</sub>]<sup>–</sup> polyborate anions are connected with each other by hydrogen bonds forming a novel zero‐dimensional (0D) dimer {2[B<sub>5</sub>O<sub>6</sub>(OH)<sub>4</sub>]<sup>–</sup>} which is further connected with [Cu(C<sub>12</sub>N<sub>2</sub>H<sub>8</sub>)<sub>2</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)]<sup>+</sup> cations through hydrogen bonds to form a one‐dimensional (1D) ribbon‐like supramolecular structure with twenty‐membered rings. The [Cu(C<sub>12</sub>N<sub>2</sub>H<sub>8</sub>)<sub>2</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)]<sup>+</sup> cations are extended through π<bold>···</bold>π stacking interactions between the 1, 10‐phenanthroline ligands forming a two‐dimensional (2D) supramolecular network. The 1D supramolecular ribbons and the 2D supramolecular layers are further extended into a three‐dimensional (3D) supramolecular framework through hydrogen‐bonding interactions. Compound <bold>1</bold> is the first example of a borate where strong hydrogen bonds and π<bold>···</bold>π stacking interactions play important coordination roles in the formation of the 3D supramolecular framework.</p> </abstract>
