    • In particular, monohydrides [HMLn] z+1, dimers [MLnx]2 z, and the parent [MLn]z species may react with a given electrophile to afford identical derivatives. For example, CpRe(CO)2H, combines with excess MeI to give [CpRe(CO)2Me2, the same product expected from a corresponding reaction with the unknown [CpRe(CO)2]2- ion; see: G. K. Yang, R. G. Bergman, J.

    • Although the average C-N-C angle in 1 is the smallest known for terminal isocyanides in a homoleptic complex, a heteroleptic Ta(I) species, namely [Ta(CNMe)2(dmpe)2Cl, dmpe, 1,2-bis (dimethylphosphano)ethane) apparently holds the record for this value. It has an average C-N-C angle of 122.0(7)°, and the isocyanides in this complex were considered to be essentially bound heteroallenes, that is, M=C=NR. See: E. M. Carnahan, S. J. Lippard, J. Am. Chem. Soc. 1992, 114, 466
