Reduction of Ar BIG ‐bian ( 1 , 1,2‐bis[(2,6‐dibenzhydryl‐4‐methylphenyl)imino]acenaphthene) with one molar equivalent of Li, Na or K in tetrahydrofuran (THF) affords corresponding radical‐anionic salts (Ar BIG ‐bian)M(THF) (M=Li, 2 ; Na, 3 ; K, 4 ). Compounds 2–4 were isolated in good yields and characterized by the elemental analysis, IR and ESR spectroscopy as well as the single‐crystal X‐Ray analysis. Bulky Ph 2 (H)C groups in Ar BIG ‐bian ligand prevent dimerization of complexes 2–4 and limit a number of coordinated THF molecules to one. In all three products a saturation of the alkali metal coordination sphere is achieved through an interaction with Ph rings of Ph 2 (H)C substituents.
