| Abstract | ||
| ABSTRACT A new pyS4 and pyN2H2S2-based iron and ruthenium complex have been synthesized and characterized in order to bind nitrogenase-relevant small molecules. These fragments were found to bind and stabilize the hydrazine small molecule which is a very important step in the nitrogenase fixation cycle. X-ray structural analysis of the hydrazine complexes deserve special interest because all types of hydrazine hydrogen atoms are involved in a system of inter- and intramolecular NH···S and NH···N hydrogen bonding with the sulfur donors (thiolate, thioether) as well as the solvate hydrazine N atoms. | ||
