The
metal halide ionic octahedron, [MX6] (M = metal
cation, X = halide anion), is considered to be the fundamental building
block and functional unit of metal halide perovskites. By representing
the metal halide ionic octahedron in halide perovskites as a super
ion/atom, the halide perovskite can be described as an extended ionic
octahedron network (ION) charge balanced by selected cations. This
new perspective of halide perovskites based on ION enables the prediction
of different packing and connectivity of the metal halide octahedra
based on different solid-state lattices. In this work, a new halide
perovskite Cs8Au3.5In1.5Cl23 was discovered on the basis of a BaTiO3-lattice ION {[InCl6][AuCl5][Au/InCl4]3}8–, which is assembled from three different ionic octahedra
[InCl6], [AuCl6], and [Au/InCl6]
and balanced by positively charged Cs cations. The success of this
ION design concept in the discovery of Cs8Au3.5In1.5Cl23 opens up a new venue for the rational
design of new halide perovskite materials.
