Abstract
The homoleptic nickel(II) bis(mercaptoimidazolyl)borate complex Ni(BmMe)2 has been readily synthesized in good yield and characterized by a combination of analytical and spectroscopic techniques. Its X-ray structure confirmed the presence of a novel [NiS4H2] species having two cis Ni···H−B interactions and an overall distorted octahedral geometry, thereby providing an unprecedented structural model compound for the active form of the nickel center in NiFe hydrogenases.
