This study details the synthesis of a novel cadmium(II) coordination polymer, poly[mu(5)-pyrazine-2,3-dicarboxylato-cadmium(II)] or [Cd(pdc)](n). The compound features a unique two-dimensional structure formed by dimeric units.
Area of Science:
- Coordination Chemistry
- Materials Science
- Inorganic Chemistry
Background:
- Pyrazine-2,3-dicarboxylate (pdc) is a versatile ligand in coordination chemistry.
- Cadmium(II) complexes are of interest for their diverse structural motifs and potential applications.
Purpose of the Study:
- To synthesize and characterize a novel coordination polymer of cadmium(II) with pyrazine-2,3-dicarboxylate.
- To elucidate the structural features and dimensionality of the resulting complex.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
- Infrared spectroscopy was employed for vibrational analysis.
Main Results:
- The title compound, poly[mu(5)-pyrazine-2,3-dicarboxylato-cadmium(II)] or [Cd(pdc)](n), was successfully synthesized.
- The cadmium(II) center exhibits a distorted octahedral coordination geometry (CdO(5)N).
- The structure consists of dimeric units bridged by carboxylate groups, which are further interconnected to form a 2D network.
Conclusions:
- The pyrazine-2,3-dicarboxylate ligand effectively bridges cadmium(II) centers to create extended structures.
- The formation of a 2D network highlights the potential of pdc as a building block in coordination polymers.

Structural Isomerism
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...
