The metal‐coordinated hydrogen isocyanide in [Cr(CO) 5 CNH] proved to be an ideal hydrogen‐bond former. Its discrete adducts with ethers and cyano complexes are surprisingly stable and some are sublimable ( 1 , [Cr] = Cr(CO) 5 ). According to IR, X‐ray structure, and 15 NMR investigations, strong N‐H…O hydrogen bonds are present. The shortest bonds are found for 2 ([Fe] = FeCp(diphos)) and 3 . In 3 , the N‐H…N bonds are symmetrical. diphos = bis(diphenylphosphino)ethane.
