catena-Poly[[aqua-cadmium(II)]-bis-(μ(2)-4-chloro-benzoato)]

Area of Science:

• Coordination Chemistry
• Materials Science
• Crystallography

Background:

• Understanding the coordination behavior of metal ions like cadmium (Cd) is crucial for developing new materials.
• Metal-organic complexes with carboxylate ligands often exhibit diverse structural motifs and potential applications.

Purpose of the Study:

• To synthesize and characterize a novel cadmium coordination complex with 4-chloro-benzoate ligands.
• To elucidate the crystal structure and supramolecular assembly of the synthesized complex.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Infrared spectroscopy was used for vibrational analysis of the complex.

Main Results:

• The complex [Cd(C(7)H(4)ClO(2))(2)(H(2)O)](n) was synthesized and characterized.
• The cadmium(II) ion exhibits a square-pyramidal coordination geometry, coordinated by a water molecule and four oxygen atoms from 4-chloro-benzoate ligands.
• The crystal structure reveals infinite polymeric chains along the c-axis formed by bridging 4-chloro-benzoate ligands.
• These chains are interconnected via water-acetate O-H⋯O hydrogen bonds, leading to the formation of layered structures in the bc plane.

Conclusions:

• The study successfully determined the crystal structure of a novel cadmium coordination polymer.
• The intricate network of hydrogen bonds plays a significant role in stabilizing the layered architecture.
• The findings contribute to the understanding of cadmium coordination chemistry and the design of metal-organic materials.
