Chiral heterocyclic ligands. Part 9. Homoconfigurational coordination polymers based on a C_2-symmetric, linear-bridging ligand

摘要

The fusion of two bornane units to a pyrazine ring gives a sterically hindered C_2-symmetric linear bridging ligand that readily assembles into one-dimensional coordination polymers; X-ray crystal structures are described for the free ligand and metallopolymers formed by reaction with silver(I) nitrate and copper(I) iodide.
