Summary
This study reveals how a novel ferrocene compound forms intricate crystal structures through multiple hydrogen bonds. These interactions lead to the formation of dimers and extended two-dimensional networks, influencing molecular conformation.
Area of Science:
- Organometallic Chemistry
- Crystal Engineering
- Supramolecular Chemistry
Background:
- Ferrocene derivatives are versatile in coordination chemistry and materials science.
- Understanding intermolecular interactions is crucial for designing crystalline materials with specific properties.
- Hydrogen bonding plays a key role in directing crystal packing and supramolecular assembly.
Purpose of the Study:
- To investigate the crystal structure and intermolecular interactions of a novel ferrocene compound.
- To elucidate the role of hydrogen bonding in the formation of supramolecular architectures.
- To analyze the conformational preferences of the ferrocene unit and its substituents.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- Analysis of hydrogen bond distances and angles to characterize intermolecular interactions.
- Conformational analysis of the ferrocene core and the ester group.
Main Results:
- The compound forms a centrosymmetric dimer via a strong N-H...O=C hydrogen bond.
- A two-dimensional network is assembled through weaker C-H...O=C hydrogen bonds involving the ester methyl group.
- The ferrocene unit exhibits an almost eclipsed 1,1'-conformation, with the ester group slightly twisted due to hydrogen bonding.
Conclusions:
- The studied ferrocene compound self-assembles into a 2D network driven by a combination of strong and weak hydrogen bonds.

01:23Properties of Organometallic Compounds
Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.
01:28Structures of Carboxylic Acid Derivatives
Structure of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

01:07Preparation of 1° Amines: Hofmann and Curtius Rearrangement Overview
In the presence of an aqueous base and a halogen, primary amides can lose the carbonyl (as carbon dioxide) and undergo rearrangement to form primary amines. This reaction, called the Hofmann rearrangement, can produce primary amines (aryl and alkyl) in high yields without contamination by secondary and tertiary amines.
02:10Carbocations
Carbocations are one of the reaction intermediates formed during several nucleophilic substitutions or elimination reactions. A carbocation is an electron-deficient species with the central carbon atom having six electrons and three bonded atoms. The central carbon in a carbocation is sp2 hybridized with trigonal planar geometry. It has an empty p orbital perpendicular to the plane of the structure that can accept electrons. Thus, carbocations act as strong electrophiles and may react with any...
01:26Preparation of 1° Amines: Hofmann and Curtius Rearrangement Mechanism
The Hofmann and Curtius rearrangement reactions can be applied to synthesize primary amines from carboxylic acid derivatives such as amides and acyl azides. In the Hofmann rearrangement, a primary amide undergoes deprotonation in the presence of a base, followed by halogenation to generate an N-haloamide. A second proton abstraction produces a stabilized anionic species, which rearranges to an isocyanate intermediate via an alkyl group migration from the carbonyl carbon to the neighboring...
01:13Carboxylic Acids to Esters: Acid-Catalyzed (Fischer) Esterification Mechanism
Carboxylic acids react with alcohols to yield esters via an acid-catalyzed condensation reaction called Fischer esterification. This is a nucleophilic acyl substitution reaction that proceeds via a tetrahedral intermediate, where a water molecule is eliminated as the leaving group.
