Bis(2-bromopyridinium) hexachloridostannate(IV)

Abstract

The asymmetric unit of the title compound, (C5H5BrN)2[SnCl6], contains one cation and one half-anion. The [SnCl6]2− anion is located on an inversion center and forms a quasi-regular octa­hedral arrangement. Hydrogen-bonding inter­actions of two kinds, viz. N—H⋯Cl—Sn and C—H⋯Cl—Sn, along with Cl⋯Br inter­actions [3.4393 (15) Å], connect the ions in the crystal structure into two-dimensional supra­molecular arrays. These supra­molecular arrays are arranged in layers approximately parallel to (110) built up from anions inter­acting with six symmetry-related surrounding cations.

A new organic–inorganic compound, ethylenediammonium hexachloridostannate(IV) p-anisaldehyde disolvate

“…The Sn-Cl2 bond involved in hydrogen bonding is slightly longer, at 2.4322 (11) Å , than the other Sn-Cl bonds [Sn-Cl1 = 2.4100 (12)Å and Sn-Cl3 = 2.4220 (11) Å ]. These results are comparable to those reported by other research groups (van Megen et al, 2013;Ali et al, 2008;Xue & Kong 2014).…”

Crystal structure and Hirshfeld analysis of (C

“…The Sn-Cl bonds are in the range of 2.4260(7)-2.4324(6) Å. All non-linear angles Cl-Sn-Cl are near 90° and are similar to those found in other octahedral SnCl6 2moieties [2][3][4][5]. The benzothiazolium cations are quasi planar and the distance between the mean parallel plans of the cations is 3.554Å.…”

“…Studies of organic-inorganic hybrid materials have received great attention in recent years, because of their ionic, electrical, magnetic and optical properties [1][2][3][4][5]. The antitumor activity of organotin complexes is also known [6].…”

Phase transitions in (C7H12N2)2[SnCl6]Cl2·1.5H2O crystal, studied by NMR and infrared spectroscopy

“…In the molecular hybrids of interest, organic groups are sandwiched between inorganic sheets and held in place either by covalent, ionic, or Van Der Waals bonding . The structural arrangement can be described as an alternation of inorganic sheets and layers of the organic molecules or ions . Hybrid compounds with organic–inorganic layer‐alternated structures have been heavily studied due to their structural flexibility and potentially useful magnetic, electrical, optical properties, and the development of fabrication techniques .…”
