Redox-active cobalt and nickel complexes

What is it about?

This paper reports some redox-active cobalt and nickel complexes with an unusual five coordinate geometry. Remarkably the complexes are air-stable which suggests more complex systems may be developed from this discovery.

Why is it important?

Redox-active systems are widely distributed in nature and synthetic analogues may be expected to find applications in molecular electronics in future high end materials. They could also act as simple visual sensors for target analytes.
