Correlated coordination and redox activity of a hemilabile noninnocent ligand in nickel complexes
Original language description
The compound [Ni(Q(M))(2)], Q(M)=4,6-di-tert-butyl-N-(2-methylthiomethylphenyl)-o-iminobenzoquinone, is a singlet diradical species with approximately planar configuration at the tetracoordinate metal atom and without any NiS bonding interaction. One-electron oxidation results in additional twofold NiS coordination (d(NiS)approximate to 2.38 angstrom) to produce a complex cation of [Ni(Q(M))(2)](PF6) with hexacoordinate Ni-II and two distinctly different mer-configurated tridentate ligands. The O,O-trans arrangement in the neutral precursor is changed to an O,O-cis configuration in the cation. The EPR signal of [Ni(Q(M))(2)](PF6) has a very large g anisotropy and the magnetic measurements indicate an S=3/2 state. The dication was structurally characterized as [Ni(Q(M))(2)](ClO4)(2) to exhibit a similar NiN2O2S2 framework as the monocation. However, the two tridentate (O,N,S) ligands are now equivalent according to the formulation [Ni-II(Q(M)(0))(2)](2+). Cyclic voltammetry reflects the
