Abstract:
In the title complex, [Ni(C9H5O6)2(C11H10N4)2]·8H2O, the Ni(II) ion exhibits site symmetry 2. It has a distorted octa-hedral coordination defined by two N atoms from two symmetry-related 1-[(1H-benzimidazol-1-yl)meth-yl]-1H-imidazole ligands and four O atoms from two symmetry-related 3,5-dicarb-oxy-benzoate anions. In the crystal, the complex mol-ecules and solvent water mol-ecules are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional structure. There are also a number of C-H⋯O inter-actions present.

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 Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
