Summary
Researchers developed new coordination polymers using hydroxamate ligands and transition metals. These materials, including Mn-ONDI-1 and CdCl-ONDI, exhibit promising electrical conductivity due to π-π stacking interactions.
Area of Science:
- Materials Science
- Inorganic Chemistry
- Supramolecular Chemistry
Background:
- Hydroxamates are emerging ligands for coordination polymer synthesis.
- The formation of strong metal-hydroxamate bonds presents challenges, limiting research on ditopic/multitopic hydroxamate coordination polymers.
Purpose of the Study:
- To synthesize novel hydroxamate coordination polymers using a bis-hydroxamate ligand with a naphthalenediimide (NDI) core.
- To investigate the structural and electrical properties of these new materials.
Main Methods:
- Synthesis of three new coordination polymers using the bis-hydroxamate ligand H2ONDI and transition metal ions (Mn2+ and Cd2+).
- Characterization of the resulting coordination polymers.
Main Results:
- Successful synthesis of three novel hydroxamate coordination polymers: Mn-ONDI-1, CdCl-ONDI, and another Cd-based polymer.
- Mn-ONDI-1 and CdCl-ONDI demonstrated interesting electrical conductivities.
- The observed conductivity is attributed to π-π stacking interactions between the NDI cores of adjacent ligands.
Conclusions:
- The study successfully expands the scope of hydroxamate coordination polymers.
- The findings highlight the potential of NDI-based hydroxamate ligands for creating conductive coordination materials.
- This work paves the way for further exploration of functional hydroxamate-based coordination polymers.

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...

01:23Properties of Organometallic Compounds
1.1K
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.

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...

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...

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...

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.
