A series of novel cobalt bis(dicarbollide) based amidines were synthesized by the nucleophilic addition of primary and secondary amines to highly activated B-N + ≡C–R triple bond of the propionitrilium derivative [8-EtC≡N-3,3′-Co(1,2-C 2 B 9 H 10 )(1′,2′-C 2 B 9 H 11 )]. The reactions with primary amines result in the formation of mixtures of  E  and  Z  isomers of amidines, whereas the reactions with secondary amines lead selectively to the  E -isomers. The crystal molecular structures of  E -[8-EtC(NMe 2 )=HN-3,3′-Co(1,2-C 2 B 9 H 10 )(1′,2′-C 2 B 9 H 11 )],  E -[8-EtC(NEt 2 )=HN-3,3′-Co(1,2- C 2 B 9 H 10 )(1′,2′-C 2 B 9 H 11 )] and  E -[8-EtC(NC 5 H 10 )=HN-3,3′-Co(1,2-C 2 B 9 H 10 )(1′,2′-C 2 B 9 H 11 )] were determined by single crystal X-ray diffraction.
