Bis(tripyrazol-1-ylmethane)nickel(II) tetra-cyanidonickelate(II) dihydrate
Abstract:
The title complex, [Ni(C(10)H(10)N(6))(2)][Ni(CN)(4)]·2H(2)O, contains an octa-hedral nickel(II) cation and a square-planar nickel(II) anion. Both the cation and the anion reside on a crystallographic center of inversion. The Ni(II) center in the cation is coordinated by six pyrazol-1-yl rings of two chelating tripyrazol-1-ylmethane [HC(pz)(3)] ligands, with Ni-N distances that range between 2.0647 (19) and 2.0828 (19) Å. The Ni(II) center in the anion is coordinated by four cyanide ligands, with Ni-C distances in the range 1.869 (2)-1.869 (3) Å. The [Ni(CN)(4)](2-) anions are linked by inversion-related water mol-ecules into extended chains that run parallel to the a axis.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

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...
