Выдержка

Two compounds containing isolated uranyl chromate and polychromate units were synthesized through room-temperature reactions of uranyl nitrate, chromium(VI) oxide, and 18-crown-6/15-crown-5 in aqueous solutions. Uranyl chromate with 18-crown-6 consists of neutral 0[(UO2)(CrO4)(H2O)3] units formed by the bidentate character of the edge sharing UrO5 bipyramid with only CrO4 and organic molecules and no additional crystallization water molecules. Uranyl polychromate with 15-crown-5 is the first inorganic compound in which [CrO4]2-, [Cr2O7]2-, and [Cr3O10]2- chromate groups are observed simultaneously.
