Influence of an electron-deficient bridging o-carborane on the electronic properties of an [FeFe] hydrogenase active site model

Dalton Trans. 2008 May 14:(18):2379-81. doi: 10.1039/b802908n. Epub 2008 Mar 11.

Abstract

The IR carbonyl stretching frequencies of [Fe2(SRS)(CO)6] complexes correlate well with their first reduction potential; an [FeFe] hydrogenase model with a very mild reduction potential has been realized by using a strongly electron deficient carborane-dithiolate bridge.
