Bis(2,2'-bipyrid-yl)bromidocopper(II) bromide bromo-acetic acid hemihydrate
Abstract:
In the title compound, [CuBr(C(10)H(8)N(2))(2)]Br·BrCH(2)COOH·0.5H(2)O, the Cu(II) ion is coordinated by four N atoms [Cu-N = 1.985 (6)-2.125 (7) Å] from two 2,2'-bipyridine ligand mol-ecules and a bromide anion [Cu-Br = 2.471 (2) Å] in a distorted trigonal-bipyramidal geometry. Short centroid-centroid distances [3.762 (5) and 3.867 (5) Å] between the aromatic rings of neighbouring cations suggest the existence of π-π inter-actions. Inter-molecular O-H⋯Br hydrogen bonds and weak C-H⋯O and C-H⋯Br inter-actions consolidate the crystal packing.

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.

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, SCN− can be...
