Summary
This study describes a rare eight-coordinate titanium(IV) compound with oxygen donors. The carbamate ligands exhibit compressed angles due to the high coordination number.
Area of Science:
- Inorganic Chemistry
- Coordination Chemistry
- Titanium Chemistry
Background:
- Eight-coordinate metal complexes are uncommon, especially those with only oxygen donors.
- Titanium(IV) typically exhibits lower coordination numbers.
- Carbamate ligands offer unique coordination possibilities.
Purpose of the Study:
- To synthesize and characterize a novel eight-coordinate titanium(IV) complex.
- To investigate the structural implications of high coordination numbers in titanium compounds.
- To analyze the coordination geometry and ligand behavior in the title compound.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular structure.
- Analysis of bond lengths, bond angles, and coordination geometry.
- Assessment of ligand conformation and disorder.
Main Results:
- A mononuclear titanium(IV) complex, [Ti(C(5)H(10)NO(2))(4)], was successfully synthesized.
- The compound features an eight-coordinate titanium center with all oxygen donors.
- Pseudo-dodecahedral coordination geometry was observed, with compressed O-C-O angles in the carbamate ligands.
- One ethyl group within the ligand showed positional disorder.
Conclusions:
- The synthesized compound represents a rare example of an eight-coordinate titanium(IV) complex with O-donors.
- The high coordination number influences the geometry and ligand parameters.
- Structural disorder in the ethyl group provides insights into crystal packing forces.

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...
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,...

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.
01:22Alkenes via Reductive Coupling of Aldehydes or Ketones: McMurry Reaction
The radical dimerization of ketones or aldehydes gives vicinal diols through a pinacol coupling reaction. However, the behavior of titanium metals used for the reaction as a source of electrons is unusual. When the reaction is carried out in the presence of titanium, diols can be isolated at low temperatures. Else titanium further reacts with diols, forming alkenes through the McMurry reaction.
02:42Valence Bond Theory
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...
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...
