Abstract
A diiron dithiolate complex holding a mu-hydride on the iron atoms and a proton on the basic site of a chelating diphosphine ligand was prepared and crystallographically characterized as a structural model of the [FeFe]-hydrogenase active site, and its molecular structure shows the H(mu)(-)...H(N)(+) distance is 3.934 A.
摘要
