Case Study

Crystal Structure Study of Alkali-Rich Metal Oxoates Including Cesium Chromate Oxide

Bender, Johannes, et al. Zeitschrift für Naturforschung B, 2010, 65(12), 1416-1426.

Several new alkali metal oxometallates featuring anions formed from tetrahedral [MO4] units were synthesized in experiments aimed at producing alkali metal suboxometallates or by thermally decomposing these compounds. Notably, cesium chromate oxide, Cs10(CrO4)2O, adopts the structure of Cs10(GeO4)2O, featuring orthochromate(IV) ions [CrO4]4- along with isolated oxide anions.
Synthesis and crystal structure of Cs10(CrO4)2O
· Cs10(CrO4)2O was obtained as xenomorphic, transparent light-brown crystals within a liquid matrix of cesium suboxides by reacting cesium metal (8.00 mmol) with Cs2CrO4 (1.14 mmol) at 523 K for 2 hours, followed by gradual cooling of the reaction mixture to room temperature at a rate of 20 K/h. The compound Cs2CrO4 was prepared through cation exchange involving aqueous solutions of K2CrO4 and CsCl. The primary aim of the reaction was to synthesize Cs9CrVIO4.
· No reaction occurred between cesium metal and Cs2CrO4 at lower temperatures, and the same was true for mixtures of cesium metal and CrO3. This indicates that the reaction initiates only at sufficiently high temperatures that promote the reduction of Cr(VI) to Cr(IV).
· Cesium chromate oxide Cs10(CrO4)2O adopts the Cs10(GeO4)2O structure type (space group P21 /c, a = 12.903(1), b = 11.4523(8), c = 19.074(3) ˚A, β = 127.903(8)◦ , V = 2223.9(4) ˚A 3 , Z = 4, R1 = 0.0326) with orthochromate(IV) anions [CrO4 ]4- and isolated oxide anions.
