Sulfur dioxide clusters structure

Only three palladium clusters were reported. Sulfur dioxide reacts with Pd(CNBu )2 to form Pd3(SO2)2(CNBu )5 (310) of structure [705] (309), and reduc-... 

Supported ruthenium carbido-cluster catalysts for the catalytic removal of nitrogen monoxide and sulfur dioxide the preparation process monitored by sulfur K-edge X-ray absorption near-edge structure... 

The preparation process of ruthenium carbido-cluster catalysts for the reduction of sulfur dioxide was traced by means of sulfur K-edge X-ray absorption near-edge structure (XANES). During the activation process, a pair of peaks at 2472.5 - 2472.8 and 2482.7 -2482.8 eV appeared. The pair was ascribed to the RuS phase. Once the catalysts were activated at 503 - 573 K, another pair of peaks at 2474.2 and 2479.2 eV appeared. The pair was assigned to the it and a transition peaks, respectively, of adsorbed SO molecules on the catalyst surface. 

BZDO enzyme also contains an iron-sulfur center. But it consists of two components an oxygenase of an (aP)3 subunit structure, in which the a contains a Rieske [2Fe-2S] cluster and a mononuclear iron site, and a reductase with one FAD and one [2Fe-2S] cluster (Yamaguchi et al. 1975 Yamaguchi and Fujisawa 1978,1980,1982). In the process of dioxidation of benzoate by BZDO, the iron ion plays an important role (Fig. 4).
