The complex [{(mu-SCH2)2N(CH2C6H4-2-Br)}Fe2(CO)6] and its N-protonated species, as structural models of the Fe-only hydrogenase active site, were identified spectroscopically and crystallographically, and their molecular structures show the 0.04-0.1 A lengthening of the three N-C bonds and an intramolecular HBr contact (2.82 Angstroms) in the crystalline state of the N-protonated species.
配合物[{(μ - SCH₂)₂N(CH₂C₆H₄ - 2 - Br)}Fe₂(CO)₆]及其N - 质子化物种作为仅含Fe的氢化酶活性位点的结构模型，通过光谱学和晶体学方法得以鉴定，其分子结构表明在N - 质子化物种的晶体状态下，三个N - C键延长了0.04 - 0.1 Å，且存在分子内HBr接触（2.82 Å）。
