Abstract:
The title complex, [Ni(NCS)(2)(C(18)H(18)N(4))]·0.5CH(3)OH, consists of two crystallographically distinct complexes and a methanol solvent mol-ecule. The Ni(II) complexes are pseudo-octa-hedral six-coordinate, with the tris-(2-pyridylmeth-yl)amine (TPA) ligand providing four N atoms and two N-bound thio-cyanates providing the final two N atoms. The distances and angles are typical for Ni(II)-TPA complexes. The compound has unit-cell parameters that are surprisingly similar to the previously reported hydrate.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
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...
