This study details the molecular structure of a zinc bromide complex with 2,2'-dipyridyldisulfide (dpds). The zinc atom forms a seven-membered chelate ring, with intermolecular hydrogen bonding creating extended chains.
Area of Science:
- Coordination Chemistry
- Crystal Engineering
- Materials Science
Background:
- 2,2 -dipyridyldisulfide (dpds) is a versatile ligand in coordination chemistry.
- Zinc bromide complexes exhibit diverse structural motifs and properties.
Purpose of the Study:
- To elucidate the molecular structure and supramolecular assembly of [ZnBr2(dpds)].
- To investigate the coordination behavior of the 2,2 -dipyridyldisulfide ligand with zinc.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed.
- Structural characterization of the synthesized zinc complex.
Main Results:
- The title compound features a seven-membered chelate ring with a tetrahedrally coordinated zinc atom.
- The disulfide group of dpds does not participate in zinc coordination.
- Intermolecular C-H⋯Br hydrogen bonding links the chelate complexes into extended chains along the [010] direction.
Conclusions:
- The study provides detailed insights into the coordination chemistry and crystal packing of zinc bromide complexes with dpds.
- The observed hydrogen bonding network highlights a common motif in the crystal engineering of such compounds.

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...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
