“…Firstly, Mn(II) is paramagnetic owing to its high spin configuration of d-orbital electrons. [33][34][35] Moreover, under the irradiation of ultraviolet light, it can exhibit good fluorescence characteristics. Furthermore, the flexibility of organic amine cations makes the compounds prone to structural phase transitions leading to changes in their physical properties.…”

“…Compared to other transition metal ions Zn 2+ and Cu 2+ , Mn-based organic–inorganic hybrid halides not only have the advantage of low raw material cost but also exhibit a unique tunable luminescent color, making them an emerging material with fascinating optical, electronic, mechanical, and other properties. − By selecting appropriate organic and inorganic components, three-dimensional (3D), two-dimensional (2D), one-dimensional (1D), and zero-dimensional (0D) structures can be obtained. Compared to high-dimensional materials, low-dimensional (0D/1D) hybrids have a higher exciton binding energy and generation energy, thus exhibiting excellent luminescence efficiency and stability. − Generally, tetrahedral-coordinated Mn 2+ emits green light, while octahedral-coordinated Mn 2+ emits red light. , As an example, Chen et al reported that the 0D Mn-based hybrid (PPh 4 ) 2 MnBr 4 displays efficient green emission and successfully prepared organic light-emitting diodes, indicating outstanding electroluminescent properties of the material . Xiong et al prepared a series of 1D Mn-based perovskite materials with octahedral geometry and strong red emission. − In addition, Ma et al reported an efficient X-ray scintillator of the 0D hybrid (C 38 H 34 P 2 )MnBr 4 , with a green emission peak of 517 nm and PLQYs of 95% .…”

Organic−inorganic hybrid halides flourish due to their thermal stability, plasticity, and optical properties. However, performance optimization through reasonable regulation has always been a challenge. Diverse anions offer a broad range of possibilities and options for the development of stimulus-responsive materials, thereby facilitating performance optimization. Here, we have successfully synthesized two organic−inorganic photoluminescent hybrid halides, (NNDP) 2 MnX 4 (NNDP = N,Ndimethylpiperidinium chloride; X = Cl, Br), with a significant enhancement in photoluminescence quantum yield (4.38% → 39.91%) via halogen modulation. The increase in quantum yield is attributed to the distortion in the [MnX 4 ] 2− tetrahedron. Furthermore, the phase-transition temperatures of (NNDP) 2 MnCl 4 and (NNDP) 2 MnBr 4 were determined as 347 and 335 K, respectively, through thermodynamic measurement. Meanwhile, the intermolecular forces of (NNDP) 2 MnCl 4 and (NNDP) 2 MnBr 4 were analyzed using a Hirshfeld surface and a two-dimensional (2D) fingerprint. This study injects new innovative ideas for the design of novel photoluminescent materials.

Magnetic capacitor, as a new type of device, has broad application prospects in fields such as magnetic field sensing, magnetic storage, magnetic field control, power electronics and so on. Traditional magnetic capacitors are mostly assembled by magnetic and capacitive materials. Magnetic capacitor made of a single material with intrinsic properties is very rare. This intrinsic property is magnetocapacitance (MC). The studies on MC effect have mainly focused on metal oxides so far. No study was reported in molecular materials. Herein, two complexes: (CETAB)2[CuCl4] (1) and (CETAB)2[CuBr4] (2) (CETAB = (2‐chloroethyl)trimethylammonium) are reported. There exist strong H‐Br and Br‐Br interactions and other weak interactions in complex 2, so the phase transition energy barrier is high, resulting in the widest thermal hysteresis loop on a molecular level to date. Furthermore, complexes 1 and 2 show large MC parameters of 0.247 and 1.614, respectively, which is the first time to observe MC effect in molecular material.
