Summary
This study details the crystal structure of a copper(II) complex, [Cu(C(14)H(14)NO(2))(2)]. The complex exhibits a square-planar geometry and forms an infinite layered supramolecular structure through intermolecular interactions.
Area of Science:
- Coordination Chemistry
- Supramolecular Chemistry
- Crystal Engineering
Background:
- Copper(II) complexes are extensively studied for their diverse coordination geometries and potential applications.
- Naphthol-derived ligands offer versatile coordination modes and influence supramolecular assembly.
- Understanding intermolecular interactions is crucial for designing advanced materials.
Purpose of the Study:
- To synthesize and characterize a novel copper(II) complex with a naphthol-derived ligand.
- To elucidate the crystal structure and supramolecular architecture of the synthesized complex.
- To investigate the role of intermolecular interactions in the formation of the observed structure.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- The coordination environment around the copper(II) ion was analyzed.
- Intermolecular interactions, specifically C-H···π interactions, were identified and characterized.
Main Results:
- The copper(II) complex, [Cu(C(14)H(14)NO(2))(2)], was synthesized and its crystal structure determined.
- The complex exhibits a distorted square-planar coordination geometry around the Cu(II) center.
- An infinite cross-linked layered supramolecular structure was observed, driven by intermolecular methyl C-H···π interactions.
Conclusions:
- The study successfully characterized a novel copper(II) complex with a unique supramolecular arrangement.
- The findings highlight the importance of weak intermolecular forces in directing crystal packing and forming extended structures.
- This research contributes to the understanding of structure-property relationships in coordination compounds.

02:36Crown Ethers
Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules take.
02:38Structure and Nomenclature of Epoxides
Cyclic ethers are heterocyclic compounds with an oxygen atom in the ring along with carbon atoms. They are named depending on the number of carbon atoms present in their ring system. Cyclic ethers with a three-membered ring system are called “oxirane”, four-membered ring systems as “oxetane”, five-membered ring systems as “oxolane”, and six-membered ring systems as “oxane”. The cyclic structure of these rings imposes angle strain, and this strain is more in the ring having a smaller number of...
02:34Structural Isomerism
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...

02:52Stereoisomerism
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...

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.
02:51Metal-Ligand Bonds
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...
