Dibromido(di-2-pyridyl sulfide-κN,N')zinc(II)

Area of Science:

• Coordination Chemistry
• Organometallic Chemistry
• Crystal Engineering

Background:

• Di-2-pyridyl sulfide (dps) is a versatile ligand in coordination chemistry.
• Zinc bromide complexes are of interest due to their diverse applications.

Purpose of the Study:

• To synthesize and characterize a new zinc bromide complex with a di-2-pyridyl sulfide ligand.
• To elucidate the molecular structure and coordination environment of the synthesized complex.

Main Methods:

• Single crystal X-ray diffraction was employed to determine the molecular structure.
• Spectroscopic techniques were used for characterization.

Main Results:

• The title compound, [ZnBr(2)(C(10)H(8)N(2)S)], was successfully synthesized and characterized.
• The crystal structure reveals a six-membered chelate ring in a boat conformation.
• The zinc atom adopts a slightly distorted tetrahedral geometry, coordinated by two bromide ions and two nitrogen atoms from the dps ligand.
• The dihedral angle between the pyridine rings is 52.7°.
• The sulfide sulfur atom does not participate in zinc coordination.

Conclusions:

• The study provides detailed structural insights into a novel zinc-dps complex.
• The findings contribute to understanding the coordination behavior of di-2-pyridyl sulfide ligands with zinc.
• The observed boat conformation highlights the structural flexibility of such chelate rings.
