Abstract

Reactions between 7-L-nido-7,8,9-C3B8H10 compounds (where L=ButNH2 and Me2NH) and [NMe3H]+[7,8-C2B9H12]− in the presence of NaH, followed by the addition of anhydrous CoCl2 and prolonged heating in diglyme at reflux, resulted in the isolation of mixed-ligand 12-vertex cobaltacarboranes [closo-(9-R2N-1,7,9-C3B8H10)-commo-2,(3′)-Co-(1′,2′-C2B9H11)] (where R=H or Me). These represent neutral, crossover complexes between metallatricarbollides and metalladicarbollides and contain amino groups attached to p-positions with respect to the metal centre.
