“…The structure of 1D perovskites consists of [BX 6 ] 4- octahedra chains with shells of organic cations, such as [DMEDA]PbBr 4 (DMEDA = N , N ′-dimethylethylenediamine), 60 and [TDMP]PbBr 4 (TDMP = trans -2,5-dimethylpiperazine). 61 0D perovskites are bulk assemblies of individual [BX 6 ] 4− octahedra at the molecular level, where the [BX 6 ] 4− octahedra are separated by organic molecules, such as (C 9 NH 20 ) 2 SnBr 4 , 62 (C 4 N 2 H 14 Br) 4 SnBr 6 . 63…”

“…Many low-dimensional halide-based organic-inorganic hybrid perovskite compounds are known [ 149 , 150 , 151 , 152 ]. They sometimes adopt a step-like (SL-type) structure which is effectively a 1D quantum wire with chains of corner-sharing octahedra “insulated” by blocks of face-sharing octahedra [ 150 ].…”

The pnictogen bond, a somewhat overlooked supramolecular chemical synthon known since the middle of the last century, is one of the promising types of non-covalent interactions yet to be fully understood by recognizing and exploiting its properties for the rational design of novel functional materials. Its bonding modes, energy profiles, vibrational structures and charge density topologies, among others, have yet to be comprehensively delineated, both theoretically and experimentally. In this overview, attention is largely centered on the nature of nitrogen-centered pnictogen bonds found in organic-inorganic hybrid metal halide perovskites and closely related structures deposited in the Cambridge Structural Database (CSD) and the Inorganic Chemistry Structural Database (ICSD). Focusing on well-characterized structures, it is shown that it is not merely charge-assisted hydrogen bonds that stabilize the inorganic frameworks, as widely assumed and well-documented, but simultaneously nitrogen-centered pnictogen bonding, and, depending on the atomic constituents of the organic cation, other non-covalent interactions such as halogen bonding and/or tetrel bonding, are also contributors to the stabilizing of a variety of materials in the solid state. We have shown that competition between pnictogen bonding and other interactions plays an important role in determining the tilting of the MX6 (X = a halogen) octahedra of metal halide perovskites in one, two and three-dimensions. The pnictogen interactions are identified to be directional even in zero-dimensional crystals, a structural feature in many engineered ordered materials; hence an interplay between them and other non-covalent interactions drives the structure and the functional properties of perovskite materials and enabling their application in, for example, photovoltaics and optoelectronics. We have demonstrated that nitrogen in ammonium and its derivatives in many chemical systems acts as a pnictogen bond donor and contributes to conferring stability, and hence functionality, to crystalline perovskite systems. The significance of these non-covalent interactions should not be overlooked, especially when the focus is centered on the rationale design and discovery of such highly-valued materials.

“…Metal halide complexes, or halometalates, represent the class of coordination compounds which, apart from fundamental interest (in particular, related to structural chemistry), attracts attention due to numerous areas of materials science where they can be applied. Those include design of ferroelectric and ferroelastic materials [1][2][3][4][5], photocatalysis [6][7][8], luminescence [9][10][11][12][13][14][15], photochromism [16,17], etc. However, the most prominent area is photovoltaics.…”

Three supramolecular bromostannates(IV) with “trapped” diiodine molecules, Cat2{[SnBr6](I2)} (Cat = Me4N+ (1), 1-MePy+ (2) and 4-MePyH (3)), were synthesized. In all cases, I2 linkers are connected with bromide ligands via halogen···halogen non-covalent interactions. Articles 1–3 were studied using Raman spectroscopy, thermogravimetric analysis, and diffuse reflectance spectroscopy. The latter indicates that 1–3 are narrow band gap semiconductors.
