Graphical Abstract

World's record: The first isolation and structural characterization of a homoleptic isocyanidemetalate dianion has been achieved with [Fe(CNXyl)₄]²⁻ (Xyl=2,6-dimethylphenyl; see structure, Fe red, N blue, C gray). Spectral and structural data indicate that metal-to-isocyanide back-bonding in this electron-rich species is the largest ever observed in a homoleptic isocyanide complex containing only terminally bound ligands.

9In particular, monohydrides [HML_n]^z+1, dimers [ML_n]₂^z, and the parent [ML_n]^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. Am. Chem. Soc. 1983, 105, 6500. In addition, [Cr(CO)₅]²⁻ and [Cr₂(CO)₁₀]²⁻ react with Ph₃SnCl to provide the same triphenylstannyl derivative, [Ph₃SnCr(CO)₅]⁻, along with Cl⁻ and [ClCr(CO)₅]⁻, respectively; see:

15bstructures for [Na([2.2.2]cryptand)]₂[Fe(CO)₄] and K₂[Fe(CO)₄] have also been reported, but both of these suffer from relatively large ranges in Fe–C bond lengths: R. G. Teller, R. G. Finke, J. P. Collman, H. B. Chin, R. Bau, J. Am. Chem. Soc. 1977, 99, 1104.

16The excellent acceptor character of CNXyl in 1 is also demonstrated by the fact that its average Fe–C bond length is 0.07-Å shorter than the average Ni–C bond length of 1.835(9) Å in the isoelectronic [Ni(CNXyl)₄],^[17] particularly because the atomic radius of iron is 0.01-Å larger than that of nickel; see: A. F. Wells, Structural Inorganic Chemistry, 5th ed., Clarendon, Oxford, UK, 1984, p. 1288.

18The other two structurally characterized monoanions of this type, [Co(CNXyl)₄]⁻,^[3b] and [Mn(CNXyl)₅]⁻,^[4] have statistically identical average isocyanide C–N bond lengths of 1.20(3) and 1.20(2) Å, respectively.

20Correlations of this type were not possible for the structurally characterized monoanions, [Co(CNXyl)₄]⁻,^[3b] [Mn(CNXyl)₅]⁻,^[4] and [V(CNXyl)₆]⁻,^[5] because they all suffered from large ranges of C-N-C angles due to substantial perturbation by cations in their respective crystalline lattices.

21Although 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.
