The first actinyl cyanide

Reaction of UO2(OTf)(2) with 5 molar equivalents of NEt4CN in acetonitrile led to the formation of the pentacyano uranyl complex [NEt4](3)[ UO2(CN)(5)] which is monomeric in the solid state with the five C-coordinated cyanide ions lying in the equatorial plane perpendicular to the linear {UO2} axis.
