K₄(CrO₄)(NO₃)₂, the first chromate(VI)-nitrate

U. Kolitsch

Abstract: K₄(CrO₄)(NO₃)₂ is the first chromate(VI)-nitrate to be reported. It contains isolated CrO₄^2- tetrahedra and NO₃^- groups linked together by K⁺ ions. The latter show a layered arrangement approximately parallel to the (001) plane. The average Cr-O, N-O and K-O bond lengths are 1.645, 1.242, and 2.905  Å, respectively. All atoms are on general positions.
