[CuSn<sub>5</sub>Sb<sub>3</sub>]<sub>2</sub><sup>4−</sup> as a dual spherical–spherical aromatic heterometallic cluster bridged <i>via</i> an antiaromatic Cu<sub>2</sub>Sn<sub>2</sub> motif
The formation of [CuSn<sub>5</sub>Sb<sub>3</sub>]<sub>2</sub><sup>4-</sup> serves as a template for heterometallic species to evaluate the resulting aromatic properties. Our results indicated that the spherical aromatic characteristics of the [CuSn<sub>5</sub>Sb<sub>3</sub>]<sup>2-</sup> building unit remained in the overall aggregate, featuring an induced shielding cone from different orientations of the external field. Furthermore, the isostructural and isoelectronic [Sn<sub>18</sub>]<sup>4-</sup> cluster sustained similar characteristics, which supported the notion of a direct relationship between [CuSn<sub>5</sub>Sb<sub>3</sub>]<sub>2</sub><sup>4-</sup> and [Sn<sub>18</sub>]<sup>4-</sup> cluster dimers. This indicated the suitable application of the pseudo-element concept relating similar connectivity between isoelectronic atoms, which could lead to further heterometallic clusters.
