“…Incorporating Fe into the A 3 Bi 2 X 9 (X = Cl, Br and I) family turns out to have a long history. Cs 3 Fe 2 Cl 9 , which is dark red in color, was reported to form two polymorphs: a 2D layered system with 𝑃3 ̅ 𝑚1 symmetry and 0D dimeric system in space group 𝑃6 3 /𝑚𝑚𝑐, 20,21 In the latter, both intradimer and interdimer magnetic interactions are present, and the two competing interactions lead to very interesting magnetic properties. In the present work, we report a new compound, Cs 3 Fe 2 Br 9 (CCDC 1575068), which is isostructural with Cs 3 Bi 2 I 9 (red) 13 and MA 3 Bi 2 I 9 (red), 14 yet is black in color.…”

The diversity of halide materials related to important solar energy systems such as CsPbX 3 (X = Cl, Br, I) is explored by introducing the transition metal element Fe. In particular a new compound, Cs 3 Fe 2 Br 9 (space group / with a = 7.5427(8) and c = 18.5849(13) Å ), has been synthesized and found to contain 0D face-sharing Fe 2 Br 9 octahedral dimers. Unlike its isomorph, Cs 3 Bi 2 I 9 , it is black in color, has a low optical bandgap of 1.65 eV and exhibits antiferromagnetic behavior below T N = 13 K. Density functional theory calculations shed further light on these properties and also predict that the material should have anisotropic transport characteristics.

“…Halo-bridged confacial bioctahedral [M 2 X 9 ] 3À anions are well-known in certain main-group and transition-metal compounds, such as in the Cs salts containing [Bi 2 I 9 ] 3À , [Ti 2 Cl 9 ] 3À or [Mo 2 Br 9 ] 3À [12], and [Fe 2 Cl 9 ] 3À [13]. A similar system has also been observed in the chlorothallate(III), [Tl 2 Cl 9 ] 3À , and was one of the earliest examples studied by X-ray crystallography [2] [12].…”

From thallium(III) bromide solution, the unsubstituted pyridinium cation yields a complex (1) with the [Tl 2 Br 9 ] 3À anionic stoichiometry. The Raman spectrum and single-crystal X-ray crystallographic analysis showed that the salt contains independent [TlBr 4 ] À and bromide anions. A variety of mono-and disubstituted pyridinium cations were also employed in similar syntheses. The 2-bromopyridinium cation gave a salt 2 with [TlBr 5 ] 2À stoichiometry, but the crystal structure revealed very weakly interacting [TlBr 4 ] À and bromide anions with a Tl ¥¥¥ Br À distance of 4.1545(6) ä. The 2-(ammoniomethyl)pyridinium and 2-amino-4-methylpyridinium cations yielded complexes containing [TlBr 5 ] 2À (3) and [TlBr 4 ] À (4) species, respectively, which were confirmed by Raman spectroscopy and X-ray crystallographic analyses. For 3, the [TlBr 5 ] 2À anion has a highly distorted trigonal bipyramidal conformation with one long axial Tl ¥¥¥ Br bond of 3.400(2) ä. Microanalytical results in conjunction with Raman spectra from a further five salts confirmed that they all contain the simple [TlBr 4 ] À anion. NÀH ¥¥¥ Br Hydrogen bonds clearly influence the nature of the anionic species obtained in these systems.

“…As mentioned in Refs. [32,33], Cs 3 Fe 2 Cl 9 is slightly sensitive to air, and thus the crystal was dealt with in the argon-filled glove box to avoid air exposure. For the crystal structure analysis, a single hexagonal plate shaped crystal with dimensions of 0.094 × 0.050 × 0.032 mm 3 was selected.…”

“…Previously, the temperature dependence of the magnetic susceptibility of a polycrystal sample was studied, and the formation of a nonmagnetic ground state with a small excitation gap was reported [31]. Micro-singlecrystal synthesis by dehydration of concentrated hydrochloric acid aqueous solutions of cesium chloride and iron chloride was reported [32,33]. However, physical properties of singlecrystal samples have not been reported so far.…”

The magnetic properties of Cs 3 Fe 2 Cl 9 single crystals were investigated by magnetic and thermal measurements. The crystal structure of Cs 3 Fe 2 Cl 9 consists of a bilayer triangular lattice of Fe 3+ ions. The analysis of magnetic susceptibility clarified that the intra-and interdimer interactions are comparable with each other, and Cs 3 Fe 2 Cl 9 is regarded as a spin-5/2 J 1 -J 2 buckled honeycomb antiferromagnet with the ferromagnetic interlayer interaction J 3 . The susceptibility for the magnetic field H ||c axis exhibits a sudden drop at the Néel temperature T N = 5.4 K, indicating a first-order magnetic phase transition. One of the characteristic features is the linear temperature dependence below T N . Furthermore, Cs 3 Fe 2 Cl 9 undergoes successive magnetic phase transitions in high magnetic fields along the c axis. We obtained a rich H-T phase diagram in which the M s /2 magnetizationplateau phase is included. These unique magnetic behaviors probably originate from the competition of magnetic interactions and the easy-axis anisotropy in the antiferromagnetic J 1 -J 2 buckled honeycomb network.
