Bis[4-(dimethyl-amino)pyridinium] tribromidochloridodimethyl-stannate(IV).

ABSTRACT: 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. The occupancies of the Br atoms are 0.721?(1) and 0.779?(1), and those of the Cl atoms are 0.279?(1) and 0.221?(1). The crystal structure involves N-H?halogen hydrogen bonds.

Bis[4-(dimethyl-amino)pyridinium] tetra-bromidobis(4-chloro-phen-yl)stannate(IV)-4-bromo-chloro-benzene (1/1).

Project description:In the title compound, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(4)Cl)(2)]·C(6)H(4)BrCl, the Sn(IV) atom in the tetra-bromidobis(4-chloro-phen-yl)stannate(IV) anion lies on a centre of inversion. The distances between the 4-(dimethyl-amino)pyridinium N atom and the Br atoms of the anion are 3.450?(2) and 3.452?(2)?Å, suggesting weak hydrogen bonding. The 4-bromo-chloro-benzene solvent mol-ecule, which is a bromination by-product from the reaction, is disordered about a twofold rotation axis with approximately equal occupancy.

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

Project description: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.
