Summary
The antimony(III) compound features three O-alkyl xanthate ligands. These ligands coordinate through sulfur atoms, creating a distorted trigonal-pyramidal structure around the antimony center.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- O-alkyl xanthates are versatile ligands in coordination chemistry.
- Antimony(III) complexes exhibit diverse coordination geometries.
- Understanding ligand coordination is crucial for predicting complex properties.
Purpose of the Study:
- To elucidate the coordination environment of antimony(III) in the title compound.
- To characterize the bonding and structural features of the [Sb(C(7)H(11)OS(2))(3)] complex.
- To investigate the role of O-alkyl xanthate ligands in antimony coordination.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular structure.
- Analysis of bond lengths and angles confirmed the coordination geometry.
- Spectroscopic methods may be employed for further characterization (though not explicitly stated in the abstract).
Main Results:
- The antimony(III) center is coordinated by three sulfur atoms from O-alkyl xanthate ligands.
- Each O-alkyl xanthate ligand acts as a monodentate ligand, coordinating solely through its sulfur atom.
- The resulting coordination geometry around antimony(III) is a distorted trigonal-pyramidal arrangement.
Conclusions:
- The study reveals a novel coordination mode for antimony(III) with O-alkyl xanthates.
- The distorted trigonal-pyramidal geometry is a key structural feature of this complex.
- This finding contributes to the understanding of antimony coordination chemistry and ligand behavior.

03:38Polyprotic Acids
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:
02:52Stereoisomerism
Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

02:54Coordination Compounds and Nomenclature
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

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 be...

02:21Naming Enantiomers
The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral center. Each enantiomer, being a distinct molecule, is assigned a unique name by the Cahn–Ingold–Prelog (CIP) rules, also called the R–S system. The prefix R- or S- attached to the chiral centers in an enantiomer is dependent on the spatial arrangement of the four substituents on the chiral center. The R–S system essentially comprises three steps:...
01:22EDTA: Chemistry and Properties
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...
