Abstract:
The reaction of Ni(NCS)2 and 4-cyano-pyridine (C6H4N2) in water leads to the formation of single crystals of the title compound, [Ni(NCS)2(C6H4N2)2(H2O)2]. The asymmetric unit consists of one NiII cation, which is located on a center of inversion, as well as one thio-cyanate anion, one 4-cyano-pyridine coligand and one water mol-ecule in general positions. The nickel cations therefore adopt trans-NiO2N4 octa-hedra, forming discrete complexes. These complexes are linked by O-H⋯S hydrogen bonds into layers that lie parallel to the bc plane. These layers are additionally linked by weak C-H⋯N inter-actions into a three-dimensional network. Powder X-ray diffraction (PXRD) indicates that an almost pure sample has been obtained. Upon heating, the title compound loses its water mol-ecules and the 4-cyano-pyridine ligands in separate steps.

02:46Crystal 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,...

02:34Structural 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...

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
