Sr 2 (OLi 2 Sr 4 )[CrN 4 ] 2 , a Nitridochromate(VI)‐Oxide with Oxygen in Tetragonal‐Bipyramidal Coordination by Lithium and Strontium Green gleaming crystals of Sr 2 (OLi 2 Sr 4 )[CrN 4 ] 2 were prepared by reaction of Li, Sr and CrN/Cr 2 N (approximate 1 : 1 mixture) with flowing nitrogen at 900 °C (molar overall composition Li : Sr : Cr = 6 : 1 : ∼3). The oxygen content results from a leak in the gas supply. The crystal structure was determined by single crystal methods (triclinic; P 1; a = 615.87(9) pm, b = 682.50(10) pm, c = 754.30(8) pm, α = 82.302(14)°, β = 75.197(10)°, γ = 70.133(13)°; Z = 1) and contains distorted tetragonal bipyramids (OLi 2 Sr 4 ) 8+ and [Cr VI N 4 ] 6– ‐tetrahedra besides Sr 2+ .
