Dibromido(di-2-pyridylamine-κN,N')mercury(II)
Abstract:
In the mol-ecule of the title compound, [HgBr(2)(C(10)H(9)N(3))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the chelating di-2-pyridylamine ligand and by two Br atoms. In the crystal structure, inter-molecular N-H⋯Br hydrogen bonds link the mol-ecules into centrosymmetric dimers. There are π-π contacts between the pyridine rings [centroid-centroid distances = 3.9662 (5) and 3.9321 (4) Å]. There also exists a C-H⋯π contact between the pyridine CH group and a pyridine ring.

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...

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
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.
