A set of structural mimics of the [Fe]-hydrogenase active site comprising all the group VIII metals, viz., [M(2-NHC(O)C₅H₄N)(CO)₂(2-S-C₅H₄N)], has been synthesized. They exist as a mixture of isomers in solution, and the relative stability of the isomers depends on the nature of the metal and the substituent at the 6-position of the pyridine ligand.

[Fe]-加氢酶的结构模拟物：VIII族金属的全套

一组[Fe]-加氢酶活性位点的结构模拟物，包括所有第VIII组金属，即[M（2-NHC（O）C ₅ H ₄ N）（CO）₂（2-SC ₅ H ₄ N）]，已经合成。它们以异构体的混合物形式存在于溶液中，异构体的相对稳定性取决于金属的性质和吡啶配体6位上的取代基。
