Poly[[tetra-kis-(μ(2)-pyrazine N,N'-dioxide-κO:O')dysprosium(III)] tris-(perchlorate)].

Area of Science:

• Inorganic Chemistry
• Materials Science
• Crystallography

Background:

• Lanthanide coordination networks are crucial for developing advanced materials.
• Understanding the structural nuances of these networks is key to predicting their properties.

Purpose of the Study:

• To synthesize and characterize a novel three-dimensional coordination network using dysprosium.
• To elucidate the coordination environment of the dysprosium cation and the role of ligands and anions.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of coordination geometry and intermolecular interactions (hydrogen bonding).

Main Results:

• A novel 3D coordination network, {[Dy(C4H4N2O2)(4)](ClO4)(3)}(n), was successfully synthesized and structurally characterized.
• The dysprosium(III) cation exhibits a distorted square-anti-prismatic coordination.
• The structure features two unique pyrazine N,N'-dioxide ligands and two unique perchlorate anions within channels.

Conclusions:

• The synthesized dysprosium coordination network is isostructural with other lanthanide analogues.
• The perchlorate anions participate in C-H⋯O hydrogen bonding within the network channels.
• This structural insight contributes to the understanding of lanthanide-based coordination polymers.
