The continual place‐changing of iron atoms in the mixed crystal phases of composition Li 4 Fe 1.04 N 2 , during which the slightly corrigated Li 2 N layers are maintained, leads in a topotactic reaction to the formation of Li 4 [FeN 2 ]. This presumably metastable nitridoferrate( II ) is one of the lesser known nitridoferrates. Li 4 [FeN 2 ] crystallizes in a defect variant of the Li 3 N structure (Li 2 Fe 0.5 □ 0.5 N), in which Li 2 N layers are bound by linearly coordinated Fe II centers.
