Summary
This study details the crystal structure of a novel iron-tin compound. The tin(IV) atom exhibits a distorted tetrahedral geometry coordinated by a ferrocene carboxylate ligand and three phenyl groups.
Area of Science:
- Organometallic Chemistry
- Coordination Chemistry
- Crystallography
Background:
- Organotin compounds are crucial in various chemical applications.
- Understanding the coordination environment of tin is vital for predicting reactivity and properties.
- Ferrocene derivatives offer unique electronic and steric properties in organometallic complexes.
Purpose of the Study:
- To elucidate the crystal structure and coordination geometry of a novel iron-tin complex.
- To characterize the bonding interactions within the title compound.
- To investigate the absence of intermolecular interactions in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular structure.
- Bond lengths and angles were precisely measured to define the coordination geometry.
- Crystallographic analysis was performed to identify intermolecular forces.
Main Results:
- The tin(IV) atom adopts a distorted tetrahedral coordination geometry.
- Coordination is achieved through one oxygen atom from a monodentate ferrocene-carboxylate ligand (Sn-O = 2.079(2) Å).
- Three carbon atoms from three phenyl groups also coordinate to tin (average Sn-C = 2.130(4) Å).
Conclusions:
- The synthesized iron-tin compound possesses a unique distorted tetrahedral tin(IV) center.
- The coordination environment is dominated by organic ligands, highlighting the role of ferrocene derivatives.
- The crystal structure lacks classical hydrogen bonds and significant intermolecular interactions, suggesting isolated molecular units.

01:18Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

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,...

03:02Colors and Magnetism
Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

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...
01:07Structure of Benzene: Kekulé Model
In 1865, August Kekule suggested the structure of benzene according to the structural theory of organic chemistry based on the three assertions—formula of benzene is C6H6, all the hydrogens of benzene are equivalent, and each carbon must have four bonds due to its tetravalency.
He proposed that benzene has a cyclic structure of six carbon atoms attached to one hydrogen atom each, with three alternating pi bonds.
