mer-Triammine trifluorido iron(III), mer-[FeF3(NH 3)3]

Abstract

Metal fluorides are scarcely soluble in liquid ammonia, and their ammine complexes are rare. The synthesis and crystal structure of the first ammine complex of an iron fluoride, the mer-triammine trifluorido iron(III), mer-[FeF3(NH3)3], is presented. The compound crystallizes in the form of colorless, needle-shaped single crystals in the monoclinic space group P21/n with Z = 4. The molecules are interconnected by strong N-H⋯F hydrogen bonds. © 2011 Verlag der Zeitschrift für Naturforschung, Tübingen.
