“…Intermetallic Cu•••Cu distances are uniform across the series and fairly short, below the interatomic distance of 2.56 Å found in metallic copper, 76 although similar distances have been found in a number of halogenido cuprates. 77,78 In contrast, E••• Cu distances are equally uniform but longer than typical Sb− Cu (e.g., 2.57 Å in [Cu 4 I 4 (Sb i Pr 3 ) 4 ] 79 ) or Bi−Cu bonds (e.g., 2.74 Å in [(Me 3 Si) 2 BiCu(PMe 3 ) 3 ] 80 ), suggesting little direct interaction between the respective metal atoms.…”

Multinary organic−inorganic metal halide materials beyond the perovskite motif can help to address both fundamental aspects such as the electronic interactions between different metalate building units and practical issues like stability and ease of preparation in this new field of research. However, such multinary compounds have remained quite rare for the halogenido pentelates, as the formation of simpler side phases can be a significant hindrance. Here, we report a family o f f o u r n e w m u l t i n a r y i o d i d o p e n t e l a t e s [PPh 4 ] 2 [ECu 2 I 7 (nitrile)] (E = Sb, Bi; nitrile = acetonitile or propionitrile), including the first metalate with a Cu−I−Sb unit. The compounds can be obtained by facile solution or mechanochemical methods and display good stability up to 160 °C. A comparison with compounds containing binary anions [EI 6 ] 3− reveals that, unexpectedly, the addition of the iodido cuprate unit causes a blue-shift in the absorption of the antimonates but a red-shift in the bismuthates. Photoluminescence investigations at 10 K show that the compounds display broad luminescence bands that correspond well with the trend in their onset of absorption. Overall, the work highlights that multinary, non-perovskite halogenido metalates can be a valuable expansion of the chemistry of metal halide perovskites.

The novel compounds K2AuPS4 (1), Tl2AuPS4 (2), K2AuAsS4 (3), and KAu5P2S8 (4) have been synthesized by direct reaction of the elements with a molten alkaline polythiophosphate(arsenate) flux at 550°C. The crystal structures of these compounds have been determined by single‐crystal X‐ray diffraction techniques. 1, 2, and 3 crystallize in the monoclinic space group P21/m. The structures of 1, 2, and 3 consist of infinite, one‐dimensional anionic chains running along the crystallographic b axis. The chains are separated by potassium or thallium ions. Neighbouring Au atoms are bridged by MS43− tetrahedra (M = P, As) in a trans orientation. Compound 4 crystallizes in the space group P21/c. The anionic chains of 4 are built up from linear AuS2 dumbbell units and PS43− tetrahedra. The chains extend along the [110] and [110] direction and are separated by charge balancing K+ cations. Each of the compounds was investigated by differential thermal analysis, FT‐IR, and solid‐state UV/Vis diffuse reflectance spectroscopy.
