Cs3Cu4In2Cl13 Nanocrystals
Abstract
<p>An effort to synthesize the Cu(I) variant of a lead-free double perovskite isostructural with Cs<sub>2</sub>AgInCl<sub>6</sub> resulted in the formation of Cs<sub>3</sub>Cu<sub>4</sub>In<sub>2</sub>Cl<sub>13</sub> nanocrystals with an unusual structure, as revealed by single-nanocrystal three-dimensional electron diffraction. These nanocrystals adopt a A<sub>2</sub>BX<sub>6</sub> structure (K<sub>2</sub>PtCl<sub>6</sub> type, termed vacancy ordered perovskite) with tetrahedrally coordinated Cu(I) ions. In the structure, 25% of the A sites are occupied by [Cu<sub>4</sub>Cl]<sup>3+</sup> clusters (75% by Cs<sup>+</sup>), and the B sites are occupied by In<sup>3+</sup>. Such a Cs<sub>3</sub>Cu<sub>4</sub>In<sub>2</sub>Cl<sub>13</sub> compound prepared at the nanoscale is not known in the bulk and is an example of a multinary metal halide with inorganic cluster cations residing in A sites. The stability of the compound was supported by density functional theory calculations that also revealed that its bandgap is direct but parity forbidden. The existence of the Cs<sub>3</sub>Cu<sub>4</sub>In<sub>2</sub>Cl<sub>13</sub> structure demonstrates that small inorganic cluster cations can occupy A sites in multinary metal halides.</p>
