Summary
The crystal structure of a zinc chloride complex with di-2-pyridyl sulfide was determined. The zinc atom is tetrahedrally coordinated, with the sulfide group not involved in binding.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Di-2-pyridyl sulfide (DPS) is a versatile ligand in coordination chemistry.
- Zinc chloride complexes are relevant in various chemical applications.
- Understanding metal-ligand interactions is crucial for designing new materials.
Purpose of the Study:
- To elucidate the crystal structure of the [ZnCl2(C10H8N2S)] complex.
- To investigate the coordination behavior of the di-2-pyridyl sulfide ligand with zinc.
- To analyze the geometric parameters of the resulting coordination compound.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Data collection and structure refinement were performed using standard crystallographic techniques.
Main Results:
- The crystal structure reveals a discrete [ZnCl2(DPS)] molecule.
- The zinc(II) ion exhibits approximate tetrahedral coordination geometry.
- Coordination involves two chloride ions and the two nitrogen atoms of the di-2-pyridyl sulfide ligand, forming a six-membered chelate ring.
- The sulfide sulfur atom of the ligand does not coordinate to the zinc center.
- The dihedral angle between the two pyridine rings of the ligand is 50.4(1)°.
Conclusions:
- The di-2-pyridyl sulfide ligand acts as a bidentate N,N-chelating ligand in this zinc complex.
- The coordination mode is consistent with previous studies on similar metal complexes.
- The determined structure provides insights into the steric and electronic properties of zinc-di-2-pyridyl sulfide systems.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Tetrahedral 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,...

02:57Coordination Number and Geometry
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.
02:42Ionic Crystal Structures
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
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...

03:45Formation of Complex Ions
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
01:20Diazonium Group Substitution with Halogens and Cyanide: Sandmeyer and Schiemann Reactions
Arenediazonium substitution reactions occur when the diazonium group is substituted by various functional groups such as halides, hydroxyl, nitrile, etc. For instance, arenediazonium salts react with copper(I) salts of chloride, bromide, or cyanide to form corresponding aryl chlorides, bromides, and nitriles. These reactions are named Sandmeyer reactions. Although the mechanism of this reaction is complicated, as illustrated in Figure 1, they are believed to progress via an aryl copper...
01:07Ladder Diagrams: Complexation Equilibria
Ladder diagrams are useful for evaluating equilibria involving metal-ligand complexes. The vertical scale of the ladder diagram represents the concentration of unreacted or free ligand, pL. The horizontal lines on the scale depict the log of stepwise formation constants for metal-ligand complexes and indicate the dominant species in all the regions.
