Abstract:
The title salt, [Ni(C3H2NS2)(C12H8N2)2]PF6·1.5C4H8O2, was the unexpected product on making an attempt to prepare an [Ni(2-mercapto-thia-zol-ate)(1,10-phenanthroline)]+ complex by reaction of [NiCl2(1,10-phen-an-throline)] with 2-mercapto-thia-zolate. In the resulting complex, the 2-mercapto-thia-zolate anion acts as a chelating ligand, which coordinates to the NiII ion with the thia-zolyl N and thiol-ate S atoms. In the crystal, π-π stacking inter-actions between the coordinating 1,10-phenanthroline mol-ecules of adjacent complexes result in a zigzag chain running parallel to the c axis. Weak C-H⋯X (X = O, F) hydrogen-bonding inter-actions between the chains and 1,4-dioxane solvent mol-ecules and PF6- counter-anions lead to the formation of sheets parallel to the ac plane.

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,...
02:42Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

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.
CFT focuses on...

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...
