Summary
Five new copper(I)/gold(I) coordination polymers were synthesized and studied. These materials exhibit distinct photoluminescence properties and structural variations, with some showing potential as sensory materials due to their thermal stability.
Area of Science:
- Inorganic Chemistry
- Materials Science
- Coordination Chemistry
Background:
- Coordination polymers based on Cu(I) and Au(I) are of interest for their unique structural and photophysical properties.
- Understanding the relationship between structure and luminescence is crucial for designing new functional materials.
Purpose of the Study:
- To synthesize and characterize novel Cu(I)/[Au(CN)2]- based coordination polymers.
- To investigate the structural, photoluminescence, and thermal properties of these new materials.
- To explore the influence of aurophilic interactions on material properties.
Main Methods:
- Synthesis of five new Cu(I)/[Au(CN)2]- coordination polymers.
- Structural characterization using X-ray diffraction.
- Photoluminescence spectroscopy to determine emission properties.
- Thermogravimetric analysis to assess thermal stability.
Main Results:
- Five coordination polymers (1-3b) were successfully prepared, exhibiting diverse structures from 1D chains to 3D frameworks.
- Materials displayed distinct luminescence colors (light green, pale blue, deep blue, violet) upon UV excitation.
- Aurophilic interactions were observed in 3D frameworks (3a, 3b) and influenced luminescence in 3a.
- Materials 1 and 3a showed thermal sensitivity, losing pyridine and THT ligands at 110°C and 95°C, respectively.
Conclusions:
- The study successfully synthesized and characterized novel Cu(I)/[Au(CN)2]- coordination polymers.
- Structural diversity, including the presence of aurophilic interactions, significantly impacts photoluminescence properties.
- The thermal sensitivity of specific materials suggests potential applications in sensory devices.

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...

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...

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...

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.

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...
