Metal and mixed-metal coordination polymers synthesized with pyrazine-2-carboxylate

Abstract

This Dalton Perspective summarizes the rich structural diversity in coordination polymers that utilize pyrazine-2-carboxylate (pca) as the linking ligand. Pyrazine-2-carboxylate has two donor groups in the form of ring nitrogens and carboxylato oxygens. This dual functionality imparts this ligand with unique and reliable networking abilities described herein. Preceding the structural details of pca based coordination polymers is a brief examination of the separate components (organic and inorganic) and the syntheses of these hybrid materials.
