Poly[ethane-1,2-diammonium tetra-μ-chlorido-cadmate(II)]

Area of Science:

• Materials Science
• Inorganic Chemistry
• Crystallography

Background:

• Coordination polymers offer tunable properties based on metal-ligand interactions.
• Layered structures in inorganic materials can exhibit unique electronic and physical characteristics.

Purpose of the Study:

• To elucidate the crystal structure and bonding of the novel coordination compound {(NH(3)CH(2)CH(2)NH(3))[CdCl(4)]}(n).
• To investigate the role of hydrogen bonding in stabilizing the layered framework.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the atomic arrangement.
• Infrared spectroscopy was used to confirm the presence of hydrogen bonding.

Main Results:

• The compound crystallizes in a layered structure with corner-sharing [CdCl(6)] octahedra forming the inorganic layers.
• Ethylenediamine cations (NH(3)CH(2)CH(2)NH(3)(2+)) are intercalated between the layers.
• An extensive N-H⋯Cl hydrogen-bonding network links the cations to the inorganic layers.
• The cadmium(II) center exhibits a distorted octahedral coordination geometry.

Conclusions:

• The described hydrogen-bonding network is crucial for the formation and stability of the layered structure.
• The distorted octahedral coordination of cadmium influences the overall structural architecture.
