“…Shortly after the discovery and magnetic characterization of CsNiCl 3 , MANiCl 3 (MA = methylammonium, CH 3 NH 3 + ), and TMANiCl 3 [TMA = tetramethylammonium, N(CH 3 ) 4 + ] were reported, , where the organoammonium cations assume the role of Cs + in separating the Ni–Cl chains. An earlier high temperature study (>80 K) of MANiCl 3 points toward antiferromagnetic intrachain coupling for that compound, like what is observed for CsNiCl 3 . In contrast, a magnetic susceptibility analysis of TMANiCl 3 suggests linear ferromagnetic interactions, unlike the antiferromagnetic behavior observed in CsNiCl 3 and MANiCl 3 .…”

We synthesize and characterize the magnetic and thermodynamic properties of the quasi one-dimensional organic–inorganic hybrid ANiCl3 compounds [A = N(CH3)4 +, CH3NH3 +, (CH3)2NH2 +, C(NH2)3 +, and CH(NH2)2 +]. Additionally, the crystal structure of (CH3)2NH2NiCl3 is reported. These materials possess chains of face-sharing NiCl6 octahedra in a triangular array. The chains run in one direction and are separated from one another by organic cations of different sizes and geometries. In accordance with the 90° superexchange model, we find that the nature of the magnetic coupling within chains can be predicted by the value of the Ni–Cl–Ni angle. As the Ni–Cl–Ni angle decreases from 90°, the magnetic interactions become increasingly antiferromagnetic. These findings provide a foundation for predicting the magnetic properties of quasi one-dimensional organic–inorganic hybrid ANiCl3 compounds.

“…Of the 3d transition metal-containing perovskites, both manganese and nickel chlorides are known to host a number of organic cations in the A site, − some of which have been studied magnetically. ,− With the exception of N(CH 3 ) 4 NiCl 3 , the aforementioned ANiCl 3 and AMnCl 3 materials are reported to exhibit one-dimensional antiferromagnetic coupling. This finding coincides with the fact that most inorganic halide hexagonal perovskitessuch as CsNiCl 3 , CsMnBr 3 , and RbCoCl 3 , to name a fewalso display dominantly antiferromagnetic intrachain interactions.…”

We synthesize four novel quasi-one-dimensional organic− inorganic hybrid iron chloride compounds (CH 3 NH 3 FeCl 3 , CH-(NH 2 ) 2 FeCl 3 , C(NH 2 ) 3 FeCl 3 , and C 3 H 5 N 2 FeCl 3 ) and characterize their structural and magnetic properties. These materials crystallize in a hexagonal perovskite-type structure, constituting a triangular array of face-sharing iron chloride octahedra chains running along the c-axis, isolated from one another by the organic cation. Through magnetization and heat capacity measurements, we find that the intrachain coupling is weakly ferromagnetic for each variant. Importantly, this work underscores the utility of solid-state chemistry approaches in synthesizing new organic−inorganic hybrid materials.

“…When M is an open-shell transition metal, the quasi-one-dimensional chains present in such hexagonal OIHPs can give rise to interesting low-dimensional magnetic phenomena. [9][10][11][12][13] We have studied several such systems-namely the AMCl3 (M = Ni 2+ , Co 2+ , Fe 2+ ) families of materials. [14][15][16] More specifically, our work focused on characterizing the nature of the one-dimensional magnetic correlations in hybrid Ni, Co, and Fe chloride hexagonal perovskites.…”

We detail the synthesis and the structural, magnetic, and ferroelectric characterization of two previously unreported hybrid halide compounds—(3-pyrrolinium)CoCl3 and (3-pyrrolinium)FeCl3. These materials crystallize in a hexagonal perovskite-type structure, consisting of face-sharing chains of metal chloride octahedra which are isolated from one another by 3-pyrrolinium rings. Through temperature and field-dependent magnetization measurements, we find that the one-dimensional coupling in the Co compound is antiferromagnetic in nature, and that of the Fe variant appears to result from competing ferromagnetic and antiferromagnetic interactions. (3-pyrrolinium)CoCl3 is found to have a ferroelectric phase with a Curie temperature of 381 K, as corroborated by dielectric constant, polarization, and second harmonic generation measurements. (3-pyrrolinium)FeCl3 also exhibits signatures of ferroelectricity below 358 K, but additional experimental evidence is required to support the transition assignment. Importantly, we report the first Co- and Fe-based organic-inorganic halide perovskite ferroelectrics of the AMX3-type. In doing so, we demonstrate an alternate route to the synthesis of novel hybrid halide materials possessing interesting magnetic or ferroelectric properties.
