Lithium complexes of 1,2-napthaquinone mono-oximes. The x-ray crystal structure of (1,2-naphthaquinone-1-oxime)(1,2-naphthaquinone-1-oximato)lithium(I)·ethanol

Abstract The complexes Li(1-nqo)· 1 2 EtOH, Li(1-nqo)(1-nqoH)·EtOH (1-nqoH = 1,2-naphthaquinone-1-oxime), and Li(2-nqo)· 1 2 EtOH, Li(2-nqo)(2-nqoH)·EtOH (2-nqoH = 1,2-naphthaquinone-2-oxime), were prepared by the interaction of the quinone oxime with lithium hydroxide. The structure of Li(1-nqo)(1-nqoH)·EtOH was determined by single-crystal X-ray diffraction techniques. The lithium atom is penta-coordinated in a distorted square pyramidal environment.
