The title compound, [Co(CN)(C3H9P)4], was obtained as a product of the reaction of [Co(PMe3)4] with a molar equivalent of 2,6-difluorobenzonitrile in diethyl ether. This compound is stable in the air for several hours, but rapidly decomposes at room temperature in solution. The cobalt(I) atom has s trigonal–bipyramidal coordination enviroment in which the cyano group and one of the PMe3 groups are in the axial positions.
