Summary
The crystal structure of [Ni(C14H8F2S2)2] shows radical monoanionic ligands and a divalent Ni2+ ion. Molecules form dyads through nickel-sulfur contacts, creating sheets stabilized by C-H...F hydrogen bonds.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Materials Science
Background:
- The study investigates the crystal structure and intermolecular interactions of a novel nickel-dithiolene complex.
- Understanding the coordination chemistry and solid-state packing of metal complexes is crucial for designing new materials.
Purpose of the Study:
- To determine the detailed crystal structure of the nickel complex [Ni(C14H8F2S2)2].
- To analyze the bonding characteristics, molecular geometry, and intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to elucidate the three-dimensional crystal structure.
- Bond lengths, bond angles, and intermolecular contacts were meticulously analyzed.
Main Results:
- The crystal structure reveals averaged S-C and C-Cchelate bond lengths consistent with radical monoanionic ligands and a divalent Ni2+ ion.
- Molecules associate into dyads via intermolecular Ni...S close contacts (3.396(2) Å).
- Dyads form sheets stabilized by intermolecular C-H...F hydrogen bonds (2.47(4) Å).
Conclusions:
- The observed bonding and structural features support the presence of radical monoanionic ligands.
- Intermolecular Ni...S contacts and C-H...F hydrogen bonds play a significant role in the self-assembly of the complex in the solid state.

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
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...

01:22EDTA: Chemistry and Properties
3.3K
Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...

Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...

01:19Complexation Equilibria: The Chelate Effect
1.2K
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

Isomerism in Complexes
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...
