Abstract

The carbide anion [CMo{N(R)Ar}3] [R = C(CD3)2CH3, Ar = C6H3Me2-3,5], is obtained by deprotonation of the corresponding methylidyne compound, [HCMo{N(R)Ar}3], and is characterized by X-ray diffraction as its {K(benzo-15-crown-5)2}+ salt, thereby providing precedent for the carbon atom as a terminal substituent in transition-metal chemistry.
