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

Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
