HCo(CO)4 and trialkylamines in hydrocarbon solution form 1:1 adducts, which may be described as NR3H+ ⋯ [Co(CO)4]- ion pairs; X-ray crystal structure determinations show that in the solid state the interacting unit NEt 3H+ ⋯ [Co(CO)4]- has an N ⋯ Co contact of 3.72 Å with the nitrogen hydrogen on the threefold axis of rotation interacting with the C3Co part of the [Co(CO) 4]- anion, in a sort of 'elongated' HCo(CO)4 structure, and a substantially similar molecular structure was found for NMe3H+ ⋯ [Co(CO)4]-, the N ⋯ Co contact being reduced to 3.39 Å.
