Abstract:
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.

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...
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly,...
