Abstract:
In the title compound, [Ni(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)(3)]·H(2)O, the Ni(II) cation is six-coordinated by a chelating 2,2'-bipyridine ligand, one carboxyl-ate O atom from a 5-nitro-isophthalate dianion and three water mol-ecules, with a slightly distorted cis-NiN(2)O(4) octa-hedral geometry. The neutral complex is isolated, in contrast to coordination polymers formed by Mn(II), Co(II) and Cu(II) with the same ligand set, but forms an extensive network of O-H⋯O hydrogen bonds between the coordinated and uncoordinated water mol-ecules and carboxyl-ate groups of the 5-nitro-isophthalate ions.

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...

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
