Pyrazine bridged benzyl dicobaloximes: Competition between π-interaction and steric crowding in crystal structure

Pyrazine (Pz) bridged benzyl dicobaloximes [ArCH2Co(dioxime) 2]2-μ-Pz [dioxime = dmgH, dpgH] have been synthesized and characterized with 1H and 13C NMR. The complexes have been synthesized by a simple procedure in one-pot directly from the corresponding benzyl aqua cobaloxime. In the crystal structure of [PhCH 2Co(dpgH)2]2-μ-Pz, two cobaloxime units are in eclipsed form whereas they were completely staggered in the reported [EtCo(dpgH)2]2-μ-Pz. This is due to the π-π interaction between the axial benzyl group and phenyl ring of the equatorial dpgH group. Both cis and trans isomer crystallized together in the crystal structure of [PhCH2Co(dpgH)(dmgH)]2-μ-Pz. The cyclic voltammetry study in [PhCH2Co(dioxime)2] 2-μ-Pz [dioxime = dmgH, dpgH] shows two cobalt center mixed together due to electron delocalization through pyrazine and behaves like a monocobaloxime and the reduction potentials are much higher than the monocobaloximes.
