Homoleptic Isocyanide Metalates

Novelties and surprises in the chemistry of metal isocyanides : The synthesis and structure determination of homoleptic isocyanide metalates M(CNXyl)_m]⁻ (M=Co, m=4; M=Mn, m=5; Xyl=2,6-Me₂C₆H₃) indicate that we need to revise our understanding of transition metal–isocyanide interactions. Further investigations will be required to determine whether these salts with isocyanide metalate ions display a chemistry as rich as that of the analogous carbonyl metalates.
