Abstract

Model compounds for the Zn sites of the β′ and the β subunits in RNA polymerase [1] were synthesized. Single crystal structures and X-ray absorption spectroscopy measurements for these two model complexes are reported. In Zn(C6H12OS2)2(ClO 4)2, the Zn is coordinated by four sulfur and two oxygen atoms. The average ZnS bond length is 2.514 Å and the ZnO bond length is 2.089 Å, which are similar to these bond distances reported for the Zn site in the β′ subunit of RNA polymerase. In Zn(C3H6NS2)2(C3 H4N2), the Zn atom is coordinated by four sulfur atoms and one nitrogen atom of an imidazole group. The average of the ZnS bond length is 2.469 Å and the ZnN bond length is 2.009 Å, which are also similar to the ZnS and ZnN bonds in the β subunits of RNA polymerase.
