Crystal structure of potassium orthoselenate(IV), K(2)SeO(3)

Crystal structure data for potassium orthoselenate(IV), K(2)SeO(3), are reported for the first time. Colorless, block-shaped crystals were grown in a potassium hydro­flux, i.e. under ultra-alkaline conditions, within 10 h. K(2)SeO(3) crystallizes isostructural with Na(2)SO(3) and K(2)TeO(3) in the t...

description Crystal structure data for potassium orthoselenate(IV), K(2)SeO(3), are reported for the first time. Colorless, block-shaped crystals were grown in a potassium hydro­flux, i.e. under ultra-alkaline conditions, within 10 h. K(2)SeO(3) crystallizes isostructural with Na(2)SO(3) and K(2)TeO(3) in the trigonal space group P [Image: see text] with lattice parameters a = 6.1063 (4) Å and c = 6.9242 (4) Å at 100 (1) K. In the trigonal–pyramidal, C (3v)-symmetric [SeO(3)](2–) anion, the bond length is 1.687 (1) Å, and the bond angle is 103.0 (1)°. Two of the three unique potassium cations exhibit a coordination number of six, and the third a coordination number of nine.
