Bis(2-bromo-pyridinium) hexa-bromido-stannate(IV).

ABSTRACT: The asymmetric unit of the title compound, (C(5)H(5)BrN)(2)[SnBr(6)], contains one cation and one half-anion. The [SnBr(6)](2-) anion is located on an inversion center and forms a quasi-regular octa-hedral arrangement. The crystal structure consists of two-dimensional supra-molecular layers assembled via hydrogen-bonding inter-actions of N-H?Br-Sn [D?A = 3.375?(13)-3.562?(13)?Å and D-H?A = 127-142°, along with C-Br?Br synthons [3.667?(2) and 3.778?(3)?Å]. These layers are parallel to the bc plane and built up from anions inter-acting extensively with the six surrounding cations.

The asymmetric unit of the title compound, (C(5)H(5)BrN)(2)[SnBr(6)], contains one cation and one half-anion. The [SnBr(6)](2-) anion is located on an inversion center and forms a quasi-regular octa-hedral arrangement. The crystal structure consists of two-dimensional supra-molecular layers assembled via hydrogen-bonding inter-actions of N-H⋯Br-Sn [D⋯A = 3.375 (13)-3.562 (13) Å and D-H⋯A = 127-142°, along with C-Br⋯Br synthons [3.667 (2) and 3.778 (3) Å]. These layers are parallel to the bc plan ...[more]

Bis(2-bromo-pyridinium) hexa-chlorido-stannate(IV).

Project description:The asymmetric unit of the title compound, (C(5)H(5)BrN)(2)[SnCl(6)], contains one cation and one half-anion. The [SnCl(6)](2-) anion is located on an inversion center and forms a quasi-regular octa-hedral arrangement. Hydrogen-bonding inter-actions of two kinds, viz. N-H⋯Cl-Sn and C-H⋯Cl-Sn, along with Cl⋯Br inter-actions [3.4393 (15) Å], connect the ions in the crystal structure into two-dimensional supra-molecular arrays. These supra-molecular arrays are arranged in layers approximately parallel to (110) built up from anions inter-acting with six symmetry-related surrounding cations.

Bis(2-meth-oxy-anilinium) hexa-bromido-stannate(IV) dihydrate.

Project description:The asymmetric unit of the title compound, (C7H10NO)2[SnBr6]·2H2O, contains one cation, one half-dianion and one lattice water mol-ecule. The [SnBr6](2-) dianion, located on an inversion center, exhibits a highly distorted octa-hedral coordination environment, with Sn-Br bond lengths ranging from 2.2426 (9) to 3.0886 (13) Å. In the crystal, O-H⋯Br, N-H⋯Br, N-H⋯O and C-H⋯Br hydrogen bonds consolidate the packing, which can be described as consisting of alternating anionic (containing dianions and lattice water mol-ecules) and cationic layers parallel to ab plane.

Synthesis, crystal structure and Hirshfeld surface of bis-(2-amino-pyridinium) hexa-chlorido-stannate(IV).

Project description:In the title mol-ecular salt, (C5H7N2)2[SnCl6], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-H⋯Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions. The thermal behaviour and the Raman spectrum of the title compound are reported.

Bis(diisopropyl-ammonium) hexa-chlorido-stannate(IV).

Project description:The title compound, (C(6)H(16)N)(2)[SnCl(6)], crystallizes with one diisopropyl-ammonium cation lying on a general position and the hexa-chloridostannate(IV) anion about a centre of inversion. The [SnCl(6)](2-) anion undergoes a slight distortion from octa-hedral symmetry as the result of the formation of four unforked charge-supported N-H⋯Cl hydrogen bonds. The hydrogen bonds between the cations and anions form layers perpendicular to [101]. These layers are built by 24-membered rings which can be classified with an R(8) (8)(24) graph-set descriptor. According to this hydrogen-bonding motif, the title compound is isostructural with (C(6)H(16)N)(2)[IrCl(6)].

Project description:The Sn(IV) atom in the title salt, (C(7)H(11)N(2))(2)[SnBr(3)(CH(3))(2)Cl], lies on a center of inversion in a tetra-gonally compressed octa-hedron; two independent Br atoms share the same site as two independent chlorine atoms so that the anion effectively has one Cl and three Br atoms.
