A nickel metalloradical bearing a phenalenyl-based tridentate ligand

Abstract A nickel(I) complex 1 bearing a phenalenyl-based tridentate ligand was synthesized. The electronic and spin structures of 1 were elucidated through electronic absorption spectra, electron spin resonance, and X-ray absorption fine structure measurements. Additionally, the metalloradical reactivity of 1 toward diphenyl disulfide and alkyl halides was also demonstrated.
