Organic–inorganic hybrids: From magnetic perovskite metal(II) halides to multifunctional metal(II) phosphonates

Low-Dimensional Hybrid Cuprous Halides Directed by Transition Metal Complex: Syntheses, Crystal Structures, and Photocatalytic Properties

“…More interestingly, the tetrahedral CuX 4 unit features high self-assembly characterization and diversiform condensation modes including corner-and edge-sharing as well as short Cu···Cu interactions. [53][54] To data, numerous [Cu x X y ] (y-x)-anionic clusters or 6-, etc, have also been reported and characterized. [67][68][69][70][71][72][73][74][75][76][77][78][79][80] Relatively, three-dimensional (3D) frameworks are rarely documented with limited topological networks.…”

“…[1][2][3][4][5][6][7][8][9][10][11] Recently, the compounds containing metal halides as inorganic moieties are important family of hybrid functional materials, especially the hybrid sliver (I) and copper(I) halides have received special attention due to the potential applications in photoluminescent, visible-light sensitizers for photovoltaic cell, chromism, etc. Generally speaking, the Cu(I) ion is able to adopt myriad coordination geometries including linear CuX 2 , CuX 3 triangle and CuX 4 tetrahedron (X = Br, I).…”

Revealing the role of Pb2+ in the stability of organic–inorganic hybrid perovskite CH3NH3Pb1−xCdxI3: an experimental and theoretical study

“…1 Thanks to these properties, perovskites have been used as sensors, catalysts and optoelectronic material. 8 Br -, I -. [5][6][7] Perovskites have a specific crystal structure with the ABX 3 formula.…”

“…Multifunctional materials are constructed from as imple ethos in which at least two species, with differing physicala nd electronic properties are combined to give an ew material, which on the basis of synergistic interactions exhibits either improved or modified physical properties or,i ns ome cases, gives rise to entirely new phenomena. [1][2][3][4][5][6][7][8][9][10] An obviouss trategy to achieve this goal is to combine cation/anion pairs with desirable properties and use this "salt" formation as the drivingf orce to pre-pare new materials.R ecent examples of multifunctional magnetic materials prepared by this strategy include: [Fe II (tren(imid) 3 )] 2 [Mn II Cl 2 Cr III (Cl 2 An) 3 ]Cl, which exhibits longrange magnetic ordering below 2.6 Ka nd an incomplete, gradual spin transition from 100 Kt o2 80 K; [11] [Fe III (qnal) 2 ] n rGO, which shows both electrical conductivity and spin-crossover behaviour; [12] and [Fe III (Iqsal) 2 ][Ni(dmit) 2 ], where there is clear evidence of the synergy between the halogen-bond stabilised spin-Peierls-like singlet formation of the [Ni(dmit) 2 ]a nions and the abrupt spin transition at 150 K [13] (Figure 1; tren-(imid) 3 = tris(2-(((Z)-(1 H-imidazol-4-yl)methylene)amino)ethyl)amine;C l 2 An = 2,5-dichloro-3,6-dioxocyclohexa-1,4-diene-1,4bis(olate);H qnal = (1-((8-quinolinylimino)methyl)-2-naphthalenol;r GO = reduced graphene oxide;H Iqsal = 5-iodo-N-(8'-quinolyl)-salicylaldinine;d mit = 4,5-dithiolato-1,3-dithiole-2-thione). In these examples, the cation of choice was as pin-crossover moiety,b ut this could easily be substituted for one with single-molecule magnet( SMM), [14] luminescent, [15] or redox-active behaviour.…”
