摘要

[Tc(NPh)Cl_3(PPh_3)_2] or [Re(NPh)Cl _3(PPh_3)_2] react with two equivalents of Na _2mnt (mnt~(2-) = 1,2-dicyanoethene-1,2-dithiolate) with formation of anionic complexes of the composition [M(NPh)(mnt)_2] ~-. The products can be isolated as large red blocks of their AsPh_4~+ salts. The complex anions contain square-pyramidal coordinated metal atoms with the phenylimido ligands in apical positions. The M-N-C bonds are almost linear. A similar phenylimido complex with an additional amino group was synthesized from [Re(NC_6H_4-4-NH _2)Cl_3(PPh_3)_2]. The presence of such substituents may allow coupling of the metal complexes to biomolecules such as peptides, proteins, or sugars, provided the M=N bonds are sufficiently stable against hydrolysis.
